Detailed Description
FTP Operation Attributes.
Operation attributes are used to control the security and performance of an FTP operation.
These features are often dependent on the capabilities of the FTP server which you are
going to access.
Typedef Documentation
typedef struct globus_i_ftp_client_operationattr_t* globus_ftp_client_operationattr_t
Operation Attributes. FTP Client attributes are used to control the parameters needed to
access an URL using the FTP protocol. Attributes are created and manipulated using the
functions in the attributes section of the library.

Function Documentation
globus_result_t globus_ftp_client_operationattr_copy (globus_ftp_client_operationattr_t * dst,
const globus_ftp_client_operationattr_t * src)
Create a duplicate of an attribute set.
The duplicated attribute set has a deep copy of all data in the attribute set, so the
original may be destroyed, while the copy is still valid.
Parameters
dst The attribute set to be initialized to the same values as src.
src The original attribute set to duplicate.
globus_result_t globus_ftp_client_operationattr_destroy (globus_ftp_client_operationattr_t *
attr)
Destroy an FTP client attribute set.
Parameters
attr A pointer to the attribute to destroy.
globus_result_t globus_ftp_client_operationattr_init (globus_ftp_client_operationattr_t *
attr)
Initialize an FTP client attribute set.
Parameters
attr A pointer to the new attribute set.
globus_result_t globus_ftp_client_operationattr_set_allocate
(globus_ftp_client_operationattr_t * attr, const globus_off_t allocated_size)
Set/Get the allocate attribute for an ftp client attribute set.
This attribute lets the user set a size to be passed to the server before a put operation.
This attribute is ignored for get operations.
Parameters
attr The attribute set to query or modify.
allocated_size The size to direct server to allocate.
globus_result_t globus_ftp_client_operationattr_set_allow_ipv6
(globus_ftp_client_operationattr_t * attr, globus_bool_t allow_ipv6)
Set/Get the allow ipv6 attribute for an ftp client attribute set.
This attribute allows client library to make use of ipv6 when possible.
Use of this is currently very experimental.
Parameters
attr The attribute set to query or modify.
allow_ipv6 GLOBUS_TRUE to allow ipv6 or GLOBUS_FALSE to disallow(default)
globus_result_t globus_ftp_client_operationattr_set_append (globus_ftp_client_operationattr_t
* attr, globus_bool_t append)
Set/Get the append attribute for an ftp client attribute set.
This attribute allows the user to append to a file on an FTP server, instead of replacing
the existing file when doing a globus_ftp_client_put() or globus_ftp_client_transfer().
This attribute is ignored on the retrieving side of a transfer, or a
globus_ftp_client_get().
Parameters
attr The attribute set to query or modify.
append The value of append attribute.
globus_result_t globus_ftp_client_operationattr_set_authorization
(globus_ftp_client_operationattr_t * attr, gss_cred_id_t credential, const char * user,
const char * password, const char * account, const char * subject)
Set/Get the authorization attribute for an ftp client attribute set.
This attribute allows the user to pass authentication information to the ftp client
library. This information is used to authenticate with the ftp server.
The Globus FTP client library supports authentication using either the GSSAPI, or standard
plaintext username and passwords. The type of authentication is determined by the URL
scheme which is used for the individual get, put, or 3rd party transfer calls.
Parameters
attr The attribute set to query or modify.
credential The credential to use for authenticating with a GSIFTP server. This may be
GSS_C_NO_CREDENTIAL to use the default credential.
user The user name to send to the FTP server. When doing a gsiftp transfer, this may
be set to NULL, and the default globusmap entry for the user's GSI identity will be
usd.
password The password to send to the FTP server. When doing a gsiftp transfer, this
may be set to NULL.
account The account to use for the data transfer. Most FTP servers do not require
this.
subject The subject name of the FTP server. This is only used when doing a gsiftp
transfer, and then only when the security subject name does not match the hostname of
the server (ie, when the server is being run by a user).
globus_result_t globus_ftp_client_operationattr_set_authz_assert
(globus_ftp_client_operationattr_t * attr, const char * authz_assert, globus_bool_t
cache_authz_assert)
Set/Get the authz_assert attribute for an ftp client attribute set.
This attribute lets the user set an AUTHORIZATION assertion to be passed to the server
Parameters
attr The attribute set to query or modify.
authz_assert The AUTHORIZATION assertion.
cache_authz_assert Boolean that specifies whether to cache this assertion for
subsequent operations
globus_result_t globus_ftp_client_operationattr_set_control_protection
(globus_ftp_client_operationattr_t * attr, globus_ftp_control_protection_t protection)
Set/Get the control channel protection attribute for an ftp client attribute set.
The control channel protection attribute allows the user to decide whether to encrypt or
integrity check the command session between the client and the FTP server. This attribute
is only relevant if used with a gsiftp URL.
Parameters
attr The attribute set to query or modify.
protection The value of control channel protection attribute.
Note
The clear and safe protection levels are treated identically, with the client
integrity checking all commands. The confidential and private protection levels are
treated identically, with the client encrypting all commands.
globus_result_t globus_ftp_client_operationattr_set_data_protection
(globus_ftp_client_operationattr_t * attr, globus_ftp_control_protection_t protection)
Set/Get the data channel protection attribute for an ftp client attribute set.
Parameters
attr The attribute set to query or modify.
protection The value of data channel protection attribute.
Note
Only safe and private protection levels are supported by gsiftp.
globus_result_t globus_ftp_client_operationattr_set_data_security
(globus_ftp_client_operationattr_t * attr, int type, void * credential)
Set/Get the data channel security context type and credential.
Parameters
attr The attribute set to query or modify.
type The type of credential. Currently only 'P' is supported, and requires a
gss_cred_id_t for the credential.
credential A credential appropriate for the type specified.
globus_result_t globus_ftp_client_operationattr_set_dcau (globus_ftp_client_operationattr_t *
attr, const globus_ftp_control_dcau_t * dcau)
Set/Get the data channel authentication attribute for an ftp client attribute set.
Data channel authentication is a GridFTP extension, and may not be supported by all
servers. If a server supports it, then the default is to delegate a credential to the
server, and authenticate all data channels with that delegated credential.
Parameters
attr The attribute set to query or modify.
dcau The value of data channel authentication attribute.
globus_result_t globus_ftp_client_operationattr_set_delayed_pasv (const
globus_ftp_client_operationattr_t * attr, globus_bool_t delayed_pasv)
Set/Get whether or not delayed passive should be used
This attribute allows the user to enable delayed passive so the server can provide the
passive address after it knows the filename to be transferred.
Parameters
attr The attribute set to query or modify.
delayed_pasv globus_bool_t
Note
Delayed passive is a GridFTP extension, and may not be supported on all FTP servers.
globus_result_t globus_ftp_client_operationattr_set_disk_stack
(globus_ftp_client_operationattr_t * attr, const char * driver_list)
Set/Get the gridftp xio driver stack used for the file storage.
This attribute allows the user to control which xio drivers will be used for file DSI
only. This is an experimental feature of the gridftp server. Only works for third party
transfers.
Parameters
attr The attribute set to query or modify.
driver_list driver list in the following format:
driver1[:driver1opts][,driver2[:driver2opts]][...]. The string 'default' will reset
the stack list to the server default.
Note
This is a GridFTP extension, and may not be supported on all FTP servers.
globus_result_t globus_ftp_client_operationattr_set_layout (globus_ftp_client_operationattr_t
* attr, const globus_ftp_control_layout_t * layout)
Set/Get the layout attribute for an ftp client attribute set.
This attribute allows the user to control the layout of a file being transferred to a
striped Grid-FTP server. The striping layout defines what regions of a file will be stored
on each stripe of a multiple-striped ftp server.
The layout attribute is used only when the data is being stored on the server (on a put or
3rd party transfer). This attribute is ignored for stream mode data transfers.
Parameters
attr The attribute set to query or modify.
layout The value of layout attribute.

globus_result_t globus_ftp_client_operationattr_set_list_uses_data_mode (const
globus_ftp_client_operationattr_t * attr, globus_bool_t list_uses_data_mode)
Set/Get whether or not list data will use the current data mode
This attribute allows the user to allow list data to be transferred using the current data
channel mode.
Parameters
attr The attribute set to query or modify.
list_uses_data_mode globus_bool_t
Note
List data transfers in nonstandard modes is a Grid-FTP extension, and may not be
supported on all FTP servers.
globus_result_t globus_ftp_client_operationattr_set_mode (globus_ftp_client_operationattr_t *
attr, globus_ftp_control_mode_t mode)
Set/Get the file transfer mode attribute for an ftp client attribute set.
This attribute allows the user to choose the data channel protocol used to transfer a
file. There are two modes supported by this library: stream mode and extended block mode.
Stream mode is a file transfer mode where all data is sent over a single TCP socket,
without any data framing. In stream mode, data will arrive in sequential order. This mode
is supported by nearly all FTP servers.
Extended block mode is a file transfer mode where data can be sent over multiple parallel
connections and to multiple data storage nodes to provide a high-performance data
transfer. In extended block mode, data may arrive out-of-order. ASCII type files are not
supported in extended block mode.
Parameters
attr The attribute set to query or modify.
mode The value of mode attribute
See also
globus_ftp_client_operationattr_set_parallelism(),
globus_ftp_client_operationattr_set_layout()
Note
Extended block mode is a Grid-FTP extension, and may not be supported on all FTP
servers.
globus_result_t globus_ftp_client_operationattr_set_net_stack
(globus_ftp_client_operationattr_t * attr, const char * driver_list)
Set/Get the gridftp xio driver stack used for the data channel.
This attribute allows the user to control which xio drivers will be used for data
transport. The driver MUST be installed and allowed by the server or the transfer/get/put
will result in an error.
Parameters
attr The attribute set to query or modify.
driver_list driver list in the following format:
driver1[:driver1opts][,driver2[:driver2opts]][...]. The string 'default' will reset
the stack list to the server default.
Note
This is a GridFTP extension, and may not be supported on all FTP servers.
globus_result_t globus_ftp_client_operationattr_set_parallelism
(globus_ftp_client_operationattr_t * attr, const globus_ftp_control_parallelism_t *
parallelism)
Set/Get the parallelism attribute for an ftp client attribute set.
This attribute allows the user to control the level of parallelism to be used on an
extended block mode file transfer. Currently, only a 'fixed' parallelism level is
supported. This is interpreted by the FTP server as the number of parallel data
connections to be allowed for each stripe of data. Currently, only the 'fixed' parallelism
type is
This attribute is ignored in stream mode.
Parameters
attr The attribute set to query or modify.
parallelism The value of parallelism attribute.

globus_ftp_client_operationattr_set_layout(),
globus_ftp_client_operationattr_set_mode()
Note
This is a Grid-FTP extension, and may not be supported on all FTP servers.
globus_result_t globus_ftp_client_operationattr_set_read_all
(globus_ftp_client_operationattr_t * attr, globus_bool_t read_all,
globus_ftp_client_data_callback_t intermediate_callback, void * intermediate_callback_arg)
Set/Get the read_all attribute for an ftp client attribute set.
This attribute allows the user to pass in a single buffer to receive all of the data for
the current transfer. This buffer must be large enough to hold all of the data for the
transfer. Only one buffer may be registered with globus_ftp_client_register_read() when
this attribute is used for a get.
In extended block mode, this attribute will cause data to be stored directly into the
buffer from multiple streams without any extra data copies.
If the user sets the intermediate callback to a non-null value, this function will be
called whenever an intermediate sub-section of the data is received into the buffer.
This attribute is ignored for globus_ftp_client_put() or
globus_ftp_client_third_party_transfer() operations.
Parameters
attr The attribute set to query or modify.
read_all The value of read_all attribute.
intermediate_callback Callback to be invoked when a subsection of the data has been
retreived. This callback may be GLOBUS_NULL, if the user only wants to be notified
when the data transfer is completed.
intermediate_callback_arg User data to be passed to the intermediate callback
function.
globus_result_t globus_ftp_client_operationattr_set_storage_module
(globus_ftp_client_operationattr_t * attr, const char * module_name, const char *
module_args)
Set/Get the gridftp storage module (DSI).
This attribute allows the user to control what backend module they use with the gridftp
server. The module MUST be implemented by the server or the transfer/get/put will result
in an error.
This attribute is ignored in stream mode.
Parameters
attr The attribute set to query or modify.
module_name The backend storage module name
module_args The backend storage module parameters
Note
This is a Grid-FTP extension, and may not be supported on all FTP servers.
globus_result_t globus_ftp_client_operationattr_set_striped (globus_ftp_client_operationattr_t
* attr, globus_bool_t striped)
Set/Get the striped attribute for an ftp client attribute set.
This attribute allows the user to force the client library to used the FTP commands to do
a striped data transfer, even when the user has not requested a specific file layout via
the layout attribute. This is useful when transferring files between servers which use the
server side processing commands ERET or ESTO to transform data and send it to particular
stripes on the destination server.
The layout attribute is used only when the data is being stored the server (on a put or
3rd party transfer). This attribute is ignored for stream mode data transfers.
Parameters
attr The attribute set to query or modify.
striped The value of striped attribute.
See also
globus_ftp_client_operationattr_set_parallelism(),
globus_ftp_client_operationattr_set_layout()
globus_ftp_client_operationattr_set_mode()
Note
This is a Grid-FTP extension, and may not be supported on all FTP servers.
globus_result_t globus_ftp_client_operationattr_set_tcp_buffer
(globus_ftp_client_operationattr_t * attr, const globus_ftp_control_tcpbuffer_t *
tcp_buffer)
Set/Get the TCP buffer attribute for an ftp client attribute set.
This attribute allows the user to control the TCP buffer size used for all data channels
used in a file transfer. The size of the TCP buffer can make a significant impact on the
performance of a file transfer. The user may set the buffer to either a system-dependent
default value, or to a fixed value.
The actual implementation of this attribute is designed to be as widely interoperable as
possible. In addition to supporting the SBUF command described in the GridFTP protocol
extensions document, it also supports other commands and site commands which are used by
other servers to set TCP buffer sizes. These are
• SITE RETRBUFSIZE
• SITE RBUFSZ
• SITE RBUFSIZ
• SITE STORBUFIZE
• SITE SBUFSZ
• SITE SBUFSIZ
• SITE BUFSIZE
This attribute is affects any type of data transfer done with the ftp client library.
Parameters
attr The attribute set to query or modify.
tcp_buffer The value of tcp_buffer attribute.
globus_result_t globus_ftp_client_operationattr_set_type (globus_ftp_client_operationattr_t *
attr, globus_ftp_control_type_t type)
Set/Get the file representation type attribute for an ftp client attribute set.
This attribute allows the user to choose the file type used for an FTP file transfer. The
file may be transferred as either ASCII or a binary image.
When transferring an ASCII file, the data will be transformed in the following way
• the high-order bit will be set to zero
• end-of line characters will be converted to a CRLF pair for the data transfer, and then
converted to native format before being returned to the user's data callbacks.
The default type for the ftp client library is binary.
Parameters
attr The attribute set to query or modify.
type The value of type attribute.
