explain_raise_or_die - send a signal to the caller and report errors
#include <libexplain/raise.h> void explain_raise_or_die(int sig); int explain_raise_on_error(int sig);
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.
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.
The explain_raise_or_die function is intended to be used in a fashion similar to the following example: explain_raise_or_die(sig);
raise(3) send a signal to the caller explain_raise(3) explain raise(3) errors exit(2) terminate the calling process
