NAME

       slurm_get_errno, slurm_perror, slurm_strerror - Slurm error handling functions

SYNTAX

       #include <slurm/slurm_errno.h>

       int slurm_get_errno ( );

       void slurm_perror (
            char *header
       );

       char * slurm_strerror (
            int errnum
       );

ARGUMENTS

       errnum A Slurm error code.

       header A pointer to a string used as a message header for printing along with an error description.

DESCRIPTION

       slurm_get_errno Return the error code as set by the Slurm API function executed.

       slurm_perror  Print  to  standard  error  the  supplied  header  followed  by  a colon followed by a text
       description of the last Slurm error code generated.

       slurm_strerror Given a Slurm error code, return a pointer to a text description of the error's meaning.

RETURN VALUE

       slurm_get_errno returns an error code or zero if no error was generated by the last Slurm  function  call
       executed.  slurm_strerror returns a pointer to a text string, which is empty if no error was generated by
       the last Slurm function call executed.

EXAMPLE

       #include <stdio.h>
       #include <slurm/slurm.h>
       #include <slurm/slurm_errno.h>

       int main (int argc, char *argv[])
       {
            /* assume Slurm API function failed here */
            fprintf (stderr, "Slurm function errno = %d\n",
                     slurm_get_errno ());
            fprintf (stderr, "Slurm function errno = %d %s\n",
                     slurm_get_errno (),
                     slurm_strerror (slurm_get_errno ()));
            slurm_perror ("Slurm function");
            exit (1);
       }

NOTE

       These functions are included in the libslurm library, which must be linked to your process for use  (e.g.
