NAME

       explain_raise_or_die - send a signal to the caller and report errors

SYNOPSIS

       #include <libexplain/raise.h>
       void explain_raise_or_die(int sig);
       int explain_raise_on_error(int sig);

DESCRIPTION

       The  explain_raise_or_die  function  is  used to call the raise(3) system call. On failure an explanation
       will be printed to stderr, obtained from the explain_raise(3) function, and then the  process  terminates
       by calling exit(EXIT_FAILURE).

       The  explain_raise_on_error  function is used to call the raise(3) system call. On failure an explanation
       will be printed to stderr, obtained from the explain_raise(3) function, but still returns to the caller.

       sig     The sig, exactly as to be passed to the raise(3) system call.

RETURN VALUE

       The explain_raise_or_die function only returns on success, see raise(3) for more information. On failure,
       prints an explanation and exits, it does not return.

       The explain_raise_on_error function always returns the value return by the wrapped raise(3) system call.

EXAMPLE

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