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);
