<Title>APPLICATION USAGE</Title>
|
|
<Para>The
|
|
<Function>DtTermSubprocReap</Function> function allows an application to install its own
|
|
<SystemItem Class="Constant">SIGCHLD</SystemItem> signal handler.
|
|
</Para>
|
|
<Para>The application must install its own
|
|
<SystemItem Class="Constant">SIGCHILD</SystemItem> signal handler and call
|
|
<Function>DtTermSubprocReap</Function> if the DtTerm widget was created with the
|
|
<Symbol>DtSubprocessTerminatorCatch</Symbol> resource set to
|
|
<SystemItem Class="Constant">False</SystemItem>.</Para>
|
|
<Para>The application must call the
|
|
<Function>DtTermSubprocReap</Function> function after performing a
|
|
<Function>wait</Function>(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.
