times, record them on the event queue, and eventually notify
higher-level software that they have occurred.  The procedures
\fBTcl_CreateEventSource\fR, \fBTcl_DeleteEventSource\fR,

The event queue: for non-threaded applications,
there is a single queue for the whole application,
containing events that have been detected but not yet serviced.  Event
sources place events onto the queue so that they may be processed in
order at appropriate times during the event loop. The event queue
guarantees a fair discipline of event handling, so that no event
source can starve the others.  It also allows events to be saved for
servicing at a future time.  Threaded applications work in a
similar manner, except that there is a separate event queue for
each thread containing a Tcl interpreter.
\fBTcl_QueueEvent\fR is used (primarily
by event sources) to add events to the event queue and
\fBTcl_DeleteEvents\fR is used to remove events from the queue without
processing them.  In a threaded application, \fBTcl_QueueEvent\fR adds
an event to the current thread's queue, and \fBTcl_ThreadQueueEvent\fR
adds an event to a queue in a specific thread.
.IP [3]
The event loop: in order to detect and process events, the application
enters a loop that waits for events to occur, places them on the event
queue, and then processes them.  Most applications will do this by
calling the procedure \fBTcl_DoOneEvent\fR, which is described in a
separate manual entry.
.PP
................................................................................
When \fIproc\fR returns 1, \fBTcl_ServiceEvent\fR will remove the
event from the event queue and free its storage.
Note that the storage for an event must be allocated by
the event source (using \fBTcl_Alloc\fR or the Tcl macro \fBckalloc\fR)
before calling \fBTcl_QueueEvent\fR, but it
will be freed by \fBTcl_ServiceEvent\fR, not by the event source.
.PP
Threaded applications work in a
similar manner, except that there is a separate event queue for

Calling \fBTcl_QueueEvent\fR in a multithreaded application adds

To add an event to another thread's queue, use \fBTcl_ThreadQueueEvent\fR.
\fBTcl_ThreadQueueEvent\fR accepts as an argument a Tcl_ThreadId argument,
which uniquely identifies a thread in a Tcl application.  To obtain the
Tcl_ThreadId for the current thread, use the \fBTcl_GetCurrentThread\fR
procedure.  (A thread would then need to pass this identifier to other
threads for those threads to be able to add events to its queue.)
After adding an event to another thread's queue, you then typically

infinite.
