Detailed Description

       GRAM Client Attribute Functions.

Macro Definition Documentation

   #define GLOBUS_GRAM_CLIENT_NO_ATTR
       Default GRAM client operation attribute. The GLOBUS_GRAM_CLIENT_NO_ATTR macro defines a constant for use
       when a user of the GRAM client API does not want to specify any non-default GRAM attributes.

Typedef Documentation

   typedef void* globus_gram_client_attr_t
       GRAM client operation attribute. The globus_gram_client_attr_t type is an opaque type describing GRAM
       attributes. It can be accessed or modified by functions in the GRAM Client Attribute Functions
       documentation.

Function Documentation

   int globus_gram_client_attr_destroy (globus_gram_client_attr_t * attr)
       Destroy a GRAM client attribute. The globus_gram_client_attr_destroy() function destroys and frees a GRAM
       client attribute. After this function returns, the value pointed to by attr is no longer valid and must
       not be used.

       Parameters
           attr A pointer to the attribute to destroy. All data associated with the attribute will be freed and
           it will be an invalid attribute.

       Returns
           Upon success, globus_gram_client_attr_destroy() destroys the attribute pointed to by the attr
           parameter and sets it to an invalid state. If an error occurs, globus_gram_client_attr_destroy()
           returns an integer error code and value of attr is unchanged.

       Return values
           GLOBUS_SUCCESS Success
           GLOBUS_GRAM_PROTOCOL_ERROR_INVALID_ATTR Invalid attribute

   int globus_gram_client_attr_get_credential (globus_gram_client_attr_t attr, gss_cred_id_t * credential)
       Get a GRAM client attribute's security credential. The globus_gram_client_attr_get_credential() function
       gets the value of the credential in an attribute and modifies the credential parameter to point to it.
       This is a shallow copy.

       Parameters
           attr The attribute set to query for its credential.
           credential An output parameter that will be initialized to point to the GSSAPI credential which the
           attr is currently using.

       Returns
           Upon success, globus_gram_client_attr_get_credential() modifies the the value pointed to by the
           credential parameter to be the same credential as that being used by the attribute named by the attr
           parameter and returns GLOBUS_SUCCESS. If an error occurs, globus_gram_client_attr_get_credential()
           returns an integer error code and the value pointed to by the credential parameter is undefined.

       Return values
           GLOBUS_SUCCESS Success
           GLOBUS_GRAM_PROTOCOL_ERROR_INVALID_ATTR Invalid attribute
           GLOBUS_GRAM_PROTOCOL_ERROR_NULL_PARAMETER Null parameter

   int globus_gram_client_attr_get_delegation_mode (globus_gram_client_attr_t attr,
       globus_io_secure_delegation_mode_t * mode)
       Get a GRAM client attribute's security credential. The globus_gram_client_attr_get_delegation_mode()
       function gets the value of the delegation_mode in an attribute and modifies the mode parameter to point
       to its value.

       Parameters
           attr The attribute set to query for its delegation_mode.
           mode An output parameter that will be set to point to the delegation mode which the attr is currently
           using.

       Returns
           Upon success, globus_gram_client_attr_get_delegation_mode() modifies the the value pointed to by the
           mode parameter as described above and returns GLOBUS_SUCCESS. If an error occurs,
           globus_gram_client_attr_get_delegation_mode() returns an integer error code and the value pointed to
           by the mode parameter is undefined.

       Return values
           GLOBUS_SUCCESS Success
           GLOBUS_GRAM_PROTOCOL_ERROR_INVALID_ATTR Invalid attribute
           GLOBUS_GRAM_PROTOCOL_ERROR_NULL_PARAMETER Null parameter

           globus_gram_client_attr_get_delegation_mode()

   int globus_gram_client_attr_init (globus_gram_client_attr_t * attr)
       Initialize a GRAM client attribute. The globus_gram_client_attr_init() function creates a new opaque
       structure that can be used to specify custom attributes for performing GRAM client operations.

       Parameters
           attr An output parameter which will be set to the newly initialized attribute.

       Returns
           Upon success, globus_gram_client_attr_init() modifies the attr parameter to point to a new GRAM
           client attribute and returns GLOBUS_SUCCESS. If an error occurs, globus_gram_client_attr_init()
           returns an integer error code and value of attr is undefined.

       Return values
           GLOBUS_SUCCESS Success
           GLOBUS_GRAM_PROTOCOL_ERROR_INVALID_ATTR Invalid attribute
           GLOBUS_GRAM_PROTOCOL_ERROR_MALLOC_FAILED Out of memory

   int globus_gram_client_attr_set_credential (globus_gram_client_attr_t attr, gss_cred_id_t credential)
       Set a GRAM client attribute's security credential. The globus_gram_client_attr_set_credential() function
       sets the value of the credential in an attribute to the GSSAPI credential named by the credential
       parameter. This is done as a shallow copy, so the value of credential must not be freed until the
       attribute will no longer be used.

       Parameters
           attr The attribute set to modify to use the credential named by the credential parameter.
           credential The GSSAPI credential to use with the attribute named by the attr parameter. This may be
           GSS_C_NO_CREDENTIAL to set the attribute to use the default security credential.

       Returns
           Upon success, globus_gram_client_attr_set_credential() modifies the the attribute pointed to by the
           attr parameter to use the credential specified by the credential parameter and returns
           GLOBUS_SUCCESS. If an error occurs, globus_gram_client_attr_set_credential() returns an integer error
           code and the attribute named by attr is unchanged.

       Return values
           GLOBUS_GRAM_PROTOCOL_ERROR_INVALID_ATTR An invalid attribute set was passed to this function.

   int globus_gram_client_attr_set_delegation_mode (globus_gram_client_attr_t attr,
       globus_io_secure_delegation_mode_t mode)
       Set a GRAM client attribute's delegation mode. The globus_gram_client_attr_set_delegation_mode() function
       sets the value of the delegation_mode in an attribute to the delegation mode in the mode parameter.

       The GRAM client supports the following delegation modes:

       • GLOBUS_IO_SECURE_DELEGATION_MODE_LIMITED_PROXY

       • GLOBUS_IO_SECURE_DELEGATION_MODE_FULL_PROXY

       Parameters
           attr The attribute set to modify to use the delegation mode in the mode parameter.
           mode The new value of the delegation mode.

       Returns
           Upon success, globus_gram_client_attr_set_delegation_mode() modifies the the attribute named by the
           attr parameter to use the delegation mode in the mode parameter and returns GLOBUS_SUCCESS. If an
           error occurs, globus_gram_client_attr_set_delegation_mode() returns an integer error code and the
           delegation_mode attribute value is unchanged.

       Return values
           GLOBUS_SUCCESS Success
           GLOBUS_GRAM_PROTOCOL_ERROR_INVALID_ATTR Invalid attribute
