Detailed Description

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.

Returns

void

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.

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

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

)

Releases the resources storing a job contact string.

Parameters

job_contact

A job contact string returned in a successful call to globus_gram_client_job_request() 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 @a extensions and @a job_contact fields of the
@a globus_gram_client_job_info_t structure pointed to by the 
@a info parameter. 

Parameters

info	A structure containing data to free.
