DESCRIPTION

14       The  explain_raise_or_die  function is used to call the raise(3) system
15       call. On failure an explanation will be  printed  to  stderr,  obtained
16       from  the explain_raise(3) function, and then the process terminates by
17       calling exit(EXIT_FAILURE).
18
19       The explain_raise_on_error function is used to call the raise(3) system
20       call.  On  failure  an  explanation will be printed to stderr, obtained
21       from the explain_raise(3) function, but still returns to the caller.
22
23       sig     The sig, exactly as to be passed to the raise(3) system call.

31       the wrapped raise(3) system call.
