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);
