termination
SYNOPSIS
#include <Dt/Term.h>
void DtTermSubprocReap(
pid_t pid,
int *stat_loc);
DESCRIPTION
The DtTermSubprocReap function allows DtTerm widgets to function cor‐
rectly 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 DtSubpro‐
cessTerminatorCatch resource set to False.
The application must call the DtTermSubprocReap function after perform‐
ing 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.
