CDE


NAME
  DtTermSubprocReap - allow a DtTerm widget to clean up after subprocess
  termination

SYNOPSIS
  #include <Dt/Term.h>
  void DtTermSubprocReap(pid_t pid,
	  int *stat_loc);

DESCRIPTION
  The DtTermSubprocReap function allows DtTerm widgets to function correctly
  in applications that have installed a SIGCHLD signal handler.

  The pid argument specifies the process ID of the child process wait(2)
  returns.

  The stat_loc argument specifies the termination information wait(2)
  returns.

RETURN VALUES
  The DtTermSubprocReap function returns no value.

APPLICATION USAGE
  The DtTermSubprocReap function allows an application to install its own
  SIGCHLD signal handler.

  The application must install its own SIGCHILD signal handler and call
  DtTermSubprocReap if the DtTerm widget was created with the
  DtSubprocessTerminatorCatch resource set to False.

  The application must call the DtTermSubprocReap function after performing a
  wait(2) (or associated function) on a terminated child process.  If the
  child process is associated with a DtTerm widget, the widget's data
  structures are cleaned up and the associated callbacks invoked.
