drmaa2_msession_get_all_queues - drmaa2_msession_get_all_queues, Returns all Univa(R) Grid Engine(TM) queues
#include "drmaa2.h"
drmaa2_queueinfo_list drmaa2_msession_get_all_queues(const drmaa2_msession monitoring_session, const drmaa2_string_list filter);
Returns a list of all queues currently stored in Grid Engine. The queue list might also contain queues which are not available for the user.
The second argument defines a filter for the queues to be returned. Only queues with names given by the filter are returned if filter is != NULL. If filter is NULL all queues are returned.
Returns a newly allocated list of queues in a drmaa2_queueinfo_list structure or NULL in case of an error. The queue list was initialized with an appropriate callback function so that drmaa2_list_free(&result) frees the complete list with all drmaa2_queueinfo objects inside. In case of an error the error number and error message can be fetched with drmaa2_lasterror(3) and drmaa2_lasterror_text().
