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.


drmaa2_string_list jsession_names = drmaa2_get_jsession_names();

if (jsession_names == NULL) {
   drmaa2_string error = drmaa2_lasterror_text();
   fprintf(stderr, "Error during fetching jsession names: %s\n", 
              "mysession", error);
} else {
   long size, i;

   size = drmaa2_list_size(jsession_names);
   for (i = 0; i < size; i++) {
      drmaa2_string jsession_name = (drmaa2_string) drmaa2_list_get(jsession_names, i);
      printf("job session: %s\n", (char *) jsession_name);
