XtToolkitThreadInitialize(3) XT FUNCTIONS XtToolkitThreadInitialize(3)NAME
XtToolkitThreadInitialize - initialize the toolkit for multiple threads
SYNTAX
Boolean XtToolkitThreadInitialize(void);
DESCRIPTION
If XtToolkitThreadInitialize was previously called, it returns. The application programmer must ensure that two or more threads do not
simultaneously attempt to call XtToolkitThreadInitialize; the effect of this is undefined. XtToolkitThreadInitialize returns True if the
host operating system has threads and the Intrinsics are thread safe.

XtAppAddSignal(3) XT FUNCTIONS XtAppAddSignal(3)NAME
XtAppAddSignal, XtRemoveSignal, XtNoticeSignal - register and remove a signal source
SYNTAX
XtSignalId XtAppAddSignal(XtAppContext app_context, XtSignalCallbackProc proc, XtPointer client_data);
void XtRemoveSignal(XtSignalId id);
void XtNoticeSignal(XtSignalId id);
ARGUMENTS
app_context
Specifies the application context.
client_data
Specifies the argument that is to be passed to the specified procedure when a signal has been raised.
id Specifies the ID returned from the corresponding XtAppAddSignal call.
proc Specifies the procedure that is to be called when the signal has been raised.
DESCRIPTION
The XtAppAddSignal function initiates a mechanism for handling signals within the context of the Intrinsics. Prior to establishing an oper-
ating system dependent signal handler the application may call XtAppAddSignal and store the returned id in a place accessible to the signal
handler.
Upon receipt of a signal from the operating system, the application may call XtNoticeSignal passing the id returned by the call to XtApp-
AddSignal.
XtNoticeSignal is the only Intrinsics function that can safely be called from a signal handler. If XtNoticeSignal is called multiple times
before the Intrinsics are able to invoke the registered callback, the callback is only called once. Logically the Intrinsics maintain
``pending'' for each registered callback. This flag is initially False and is set to True by XtNoticeSignal; the Intrinsics invoke the
callback whenever the flag is True, and the flag is set to False just before the callback is invoked.
The XtRemoveSignal function is called to remove the specified Intrinsics signal handler. The client should disable the source of the signal
before calling XtRemoveSignal.
