Function Documentation
globus_result_t globus_xio_attr_init (globus_xio_attr_t *attr)
Intialize a globus xio attribute.
Parameters:
attr upon return from this function this out parameter will be initialized. Once the
user is finished with the attribute they should make sure they destroy it in order to
free resources associated with it.
References globus_xio_attr_init().
globus_result_t globus_xio_attr_cntl (globus_xio_attr_tattr, globus_xio_driver_tdriver,
intcmd, ...)
Manipulate the values associated in the attr. This function provides a means to access the
attr structure. What exactly this function does is determined by the value in the
parameter cmd and the value of the patameter driver. When the driver parameter is NULL it
indicates that this function applies to general globus xio values. If it is not NULL it
indicates that the function will effect driver specific values. Each driver is resonsible
for defining its own enumeration of values for cmd and the var args associated with that
command.
Parameters:
attr the attribute structure to be manipulated.
driver This parameter indicates which driver the user would like to perform the
requested operation. If this parameter is NULL this request will be scoped to general
attribure functions.
cmd an enum that determines what specific operation the user is requesting. Each
driver will determine the value for this enumeration.
References globus_xio_attr_cntl().
globus_result_t globus_xio_attr_copy (globus_xio_attr_t *dst, globus_xio_attr_tsrc)
Copy an attribute structure.
References globus_xio_attr_copy().
globus_result_t globus_xio_attr_destroy (globus_xio_attr_tattr)

then be used to accept connections.
Parameters:
server An out parameter. Once the function successfully returns this will point to a
valid server object.
server_attr an attributre structure used to alter the default server intialization.
This will mostly be used in a driver specific manner. can be NULL.

contact_string an out varibale. Will point to a newly allocated string on success.
must be freed by the caller.
References globus_xio_server_get_contact_string().
globus_result_t globus_xio_server_register_close (globus_xio_server_tserver,
globus_xio_server_callback_tcb, void *user_arg)
post a close on a server object This function registers a close operation on a server.
When the user function pointed to by parameter cb is called the server object is closed.
References globus_xio_server_register_close().

Parameters:
handle The handle created with globus_xio_handle_create() or
globus_xio_server_register_accept() that is to be opened.
attr how to open attribute. can be NULL
cb The function to be called when the open operation completes.
user_arg A user pointer that will be threaded through to the callback.
contact_string An url describing the resource. NULL is allowed. Drivers interpret the
various parts of this url as descibed in their documentation. An alternative form is
also supported: if contact_string does not specify a scheme (e.g. http://) and it
contains a ':', it will be parsed as a host:port pair. if it does not contain a ':',
it will be parsed as the path
the following are examples of valid formats:
<path to file>
host-name ':' <service or port>
'file:' <path to file>
<scheme> '://' [ '/' [ <path to resource> ] ]
<scheme> '://' location [ '/' [ <path to resource> ] ]
location:
[ auth-part ] host-part
auth-part:
<user> [ ':' <password> ] '@'
host-part:
[ '<' <subject> '>' ] host-name [ ':' <port or service> ]
host-name:
<hostname> | <dotted quad> | '[' <ipv6 address> ']'
Except for use as the above delimeters, the following special characters MUST be encoded
with the %HH format where H == hex char.
'/' and '@' in location except subject
'<' and '>' in location
':' everywhere except ipv6 address and subject
'%' everywhere (can be encoded with %HH or %%)
