explain_setsid_or_die

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) system 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 setsid(2) for more information. On failure, prints an explanation and
       exits, 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();

SEE ALSO

       setsid(2)
	       creates a session and sets the process group ID

       explain_setsid(3)
	       explain setsid(2) errors

       exit(2) terminate the calling process
