flux_shell_task_get_info(3)¶

SYNOPSIS¶

#include <flux/shell.h>

int flux_shell_task_get_info (flux_shell_task_t *task,
                              char **json_str);

int flux_shell_task_info_unpack (flux_shell_task_t *task,
                                 const char *fmt, ...);

Returns task info either as a json string (specified below) or using Jansson-style parameters. The structure of the former is:

"localid":i,
"rank":i,
"state":s,
"pid":I,
"wait_status":i,
"exitcode":i,
"signaled":i

Returns 0 on success and -1 on failure. A failure will not necessarily set errno.
