Detailed Description

       GRAM Client API.

       The resource management API provides function for requesting that a job be started or
       terminated, as well as for requesting information about the status of a job.

Function Documentation

   void globus_gram_client_debug (void)
       Enable GRAM debugging. The globus_gram_client_debug() function enables the displaying of
       internal GRAM debug messages to standard output. Most of the information printed by this
       debugging system is related to errors that occur during GRAM Client API functions. The
       messages printed to standard output are not structured in any way.

   const char* globus_gram_client_error_string (int error_code)
       Get a description of a a GRAM error code. The globus_gram_client_error_string() function
       takes a GRAM error code value and returns the associated error code string. The string is
       statically allocated by the Globus GRAM Client library and should not be modified or
       freed. The string is intended to complete a sentence of the form '[operation] failed
       because ...'

       Parameters
           error_code The error code to translate into a string.

       Returns
           The globus_gram_client_error_string() function returns a static string containing an
           explanation of the error.

   int globus_gram_client_job_contact_free (char * job_contact)
       Free a job contact string. The globus_gram_client_job_contact_free() function frees a job
       contact string that was allocated by a call to one of the functions in the
       globus_gram_client_job_request() family. The free() function can be used in place of this
       function. After this function returns, the string pointed to by the job_contact parameter
       has an undefined value.

       Parameters
           job_contact Pointer to a job contact string returned by a GRAM client API function.

       Returns
           This function always returns GLOBUS_SUCCESS.

       Return values
           GLOBUS_SUCCESS Success

   void globus_gram_client_job_info_destroy (globus_gram_client_job_info_t * info)
       Free memory associated with a globus_gram_client_job_info_t structure. The
       globus_gram_client_job_info_destroy() function frees data pointed to by the extensions and
       job_contact fields of the globus_gram_client_job_info_t structure pointed to by the info
       parameter.

       Parameters
           info A structure containing data to free.

   int globus_gram_client_set_credentials (gss_cred_id_t new_credentials)
       Set the default GRAM credential. The globus_gram_client_set_credentials() function causes
       subsequent GRAM operations to use the GSSAPI credential new_credentials. These operations
       include job requests, job signals, callback registration, and job state callbacks. After
       this function returns, the caller must not use the credential, as it may be freed by GRAM
       when it is no longer needed.

       Parameters
           new_credentials New GSSAPI credential to use.

       Returns
           Upon success, globus_gram_client_set_credentials() returns GLOBUS_SUCCESS. There are
           no error values returned by this fucntion.

       Return values
           GLOBUS_SUCCESS Success

   int globus_gram_client_version (void)
       Return GRAM protocol version. The globus_gram_client_version() function returns the
       version of the GRAM protocol understood by this implementation.

       Returns
           The integer protocol revision.
