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);
