explain_setsid_or_die(3)   Library Functions Manual   explain_setsid_or_die(3)

NAME
       explain_setsid_or_die - sets process group ID and report	errors

SYNOPSIS
       #include	<libexplain/setsid.h>
       pid_t explain_setsid_or_die(void);
       pid_t explain_setsid_on_error(void);

DESCRIPTION
       The explain_setsid_or_die function is used to call the setsid(2)	system
       call. On	failure	an explanation will be	printed	 to  stderr,  obtained
       from the	explain_setsid(3) function, and	then the process terminates by
       calling exit(EXIT_FAILURE).

       The explain_setsid_on_error function is used to call the	setsid(2) sys-
       tem call. On failure an explanation will	be printed to stderr, obtained
       from the	explain_setsid(3) function, but	still returns to the caller.

RETURN VALUE
       The explain_setsid_or_die function only returns on  success,  see  set-
       sid(2)  for more	information. On	failure, prints	an explanation and ex-
       its, it does not	return.

       The explain_setsid_on_error function always returns the value return by
       the wrapped setsid(2) system call.

EXAMPLE
       The  explain_setsid_or_die function is intended to be used in a fashion
       similar to the following	example:
	      explain_setsid_or_die();
