Name
explain_kill_or_die - send signal to a process and report errors
Synopsis
#include <libexplain/kill.h>
void explain_kill_or_die(pid_t pid, int sig);
int explain_kill_on_error(pid_t pid, int sig);
Description
The explain_kill_or_die function is used to call the kill(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_kill(3) function, and then the process terminates by calling exit(EXIT_FAILURE).
The explain_kill_on_error function is used to call the kill(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_kill(3) function, but still returns to the caller.
- pid
The pid, exactly as to be passed to the kill(2) system call.
sig
The sig, exactly as to be passed to the kill(2) system call.
Return Value
The explain_kill_or_die function only returns on success, see kill(2) for more information. On failure, prints an explanation and exits, it does not return.
The explain_kill_on_error function always returns the value return by the wrapped kill(2) system call.
Example
The explain_kill_or_die function is intended to be used in a fashion similar to the following example:
-
explain_kill_or_die(pid, sig);
