KILLPG(3P)                POSIX Programmer's Manual               KILLPG(3P)

PROLOG         top

       This manual page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the
       corresponding Linux manual page for details of Linux behavior), or
       the interface may not be implemented on Linux.

NAME         top

       killpg — send a signal to a process group

SYNOPSIS         top

       #include <signal.h>

       int killpg(pid_t pgrp, int sig);

DESCRIPTION         top

       The killpg() function shall send the signal specified by sig to the
       process group specified by pgrp.

       If pgrp is greater than 1, killpg(pgrp, sig) shall be equivalent to
       kill(−pgrp, sig). If pgrp is less than or equal to 1, the behavior of
       killpg() is undefined.

RETURN VALUE         top

       Refer to kill(3p).

ERRORS         top

       Refer to kill(3p).

       The following sections are informative.

EXAMPLES         top

   Sending a Signal to All Other Members of a Process Group
       The following example shows how the calling process could send a
       signal to all other members of its process group. To prevent itself
       from receiving the signal it first makes itself immune to the signal
       by ignoring it.

           #include <signal.h>
           #include <unistd.h>
           ...
               if (signal(SIGUSR1, SIG_IGN) == SIG_ERR)
                   /* Handle error */;

               if (killpg(getpgrp(), SIGUSR1) == −1)
                   /* Handle error */;"

APPLICATION USAGE         top

       None.

RATIONALE         top

       None.

FUTURE DIRECTIONS         top

       None.
