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);
