explain_setresuid_or_die(3)Library Functions Manualexplain_setresuid_or_die(3)

NAME
       explain_setresuid_or_die	- set r/e/s user ID and	report errors

SYNOPSIS
       #include	<libexplain/setresuid.h>
       void explain_setresuid_or_die(uid_t ruid, uid_t euid, uid_t suid);
       int explain_setresuid_on_error(uid_t ruid, uid_t	euid, uid_t suid);

DESCRIPTION
       The  explain_setresuid_or_die function is used to call the setresuid(2)
       system call. On failure an explanation will be printed to  stderr,  ob-
       tained  from  the  explain_setresuid(3)	function, and then the process
       terminates by calling exit(EXIT_FAILURE).

       The explain_setresuid_on_error function is  used	 to  call  the	setre-
       suid(2)	system	call.  On  failure  an	explanation will be printed to
       stderr, obtained	from the explain_setresuid(3) function,	but still  re-
       turns to	the caller.

       ruid    The  ruid,  exactly  as to be passed to the setresuid(2)	system
	       call.

       euid    The euid, exactly as to be passed to  the  setresuid(2)	system
	       call.

       suid    The  suid,  exactly  as to be passed to the setresuid(2)	system
	       call.

RETURN VALUE
       The explain_setresuid_or_die function only returns on success, see  se-
       tresuid(2)  for more information. On failure, prints an explanation and
       exits, it does not return.

       The explain_setresuid_on_error function always returns the value	return
       by the wrapped setresuid(2) system call.

EXAMPLE
       The explain_setresuid_or_die function is	intended to be used in a fash-
       ion similar to the following example:
	      explain_setresuid_or_die(ruid, euid, suid);

       setresuid(2)
	       set real, effective and saved user ID

       explain_setresuid(3)
	       explain setresuid(2) errors
