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       attr is no longer valid and must not be used.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

   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
