ADDCHILDHANDLER(3A)                           ADDCHILDHANDLER(3A)



  NAME
       AddChildHandler - add a child handler for a process


  SYNOPSIS
       AddChildHandler (pid, func, arg)
       int pid;
       int (*func)();
       int arg;

  DESCRIPTION
       AddChildHandler registers a child handler process for the
       given pid.  When the child exits, the exit status is saved,
       and a work procedure is added, which will call the handling
       routine for the child.  This avoids executing a lot of code
       in the signal handling routine, and allows the child handler
       to be scheduled around the event processing of the X
       toolkit.

       The calling sequence of the handler are:

            handler (arg, status, pid)
            int arg;
            int status;
            int pid;

       The arg is the user-provided argument to AddChildHandler.
       The status is its exit status, and pid is the process ID of
       the child process.  See wait(2) for details on the format of
       status.
