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 pro- cess 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 associ- ated with a DtTerm widget, the widget's data structures are cleaned up and the associated callbacks invoked. SEE ALSO DtTerm(5), DtTerm(3); signal(5), wait(2).
