NAME
       explain_nice_or_die - change process priority and report	errors

SYNOPSIS
       #include	<libexplain/nice.h>
       int explain_nice_or_die(int inc);
       int explain_nice_on_error(int inc);

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

       The explain_nice_on_error function is used to call the  nice(2)	system
       call.  On  failure  an  explanation will	be printed to stderr, obtained
       from the	explain_nice(3)	function, but still returns to the caller.

       inc     The inc,	exactly	as to be passed	to the nice(2) system call.

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

       The explain_nice_on_error function always returns the value  return  by
       the wrapped nice(2) system call.

EXAMPLE
       The  explain_nice_or_die	 function  is intended to be used in a fashion
       similar to the following	example:
	      int result = explain_nice_or_die(inc);
