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);
       }
