Manual Pages for UNIX Operating System command usage for man killpg

Standard C Library Functions                           killpg(3C)



NAME
     killpg - send signal to a process group

SYNOPSIS
     #include 

     int killpg(pid_t pgrp, int sig);


DESCRIPTION
     The killpg() function sends the signal sig  to  the  process
     group pgrp. See signal.h(3HEAD) for a list of signals.


     The real or effective user ID of the  sending  process  must
     match  the  real  or saved set-user ID of the receiving pro-
     cess, unless the effective user ID of the sending process is
     the  privileged  user.  A  single  exception  is  the signal
     SIGCONT, which may always be sent to any descendant  of  the
     current process.

RETURN VALUES
     Upon successful completion, 0 is returned. Otherwise, -1  is
     returned and errno is set to indicate the error.

ERRORS
     The killpg() function will fail and no signal will  be  sent
     if:

     EINVAL    The sig argument is not a valid signal number.


     EPERM     The effective user ID of the  sending  process  is
               not  privileged  user,  and  neither  its real nor
               effective user ID matches the real or  saved  set-
               user ID of one or more of the target processes.


     ESRCH     No processes were found in the  specified  process
               group.
