drmaa2_get_jsession_names
- drmaa2_get_jsession_names(3), Returns all available persistent job sessions.
#include "drmaa2.h"
drmaa2_string_list drmaa2_get_jsession_names();
Fetches all available persistent DRMAA2 job session names from the Univa(R) Grid Engine(TM)
master process. There is no previous call needed to perform this action. In case of success a drmaa2_string_list
with all DRMAA2 job session names is returned. Those job session names can be used for opening a DRMAA2 job session with the drmaa2_open_jsession(3) function.
Note: In Univa(R) Grid Engine(TM)
DRMAA2 job sessions can be listed, created, and deleted also by qconf(3) calls.
On success a drmaa2_string_list
is returned. It might contain 0 or more entries. The string list was initialized with a callback, which deletes all allocated strings when the list is freed with drmaa2_list_free(3). In case of an failure the error code indicating the failure reason and a description is stored for the calling thread. The failure description can be fetched with the drmaa2_lasterror_text(3) function call. The failure code can be fetched with the drmaa2_lasterror(3) call.
