-.SH NAME
-Tcl_DoWhenIdle, Tcl_CancelIdleCall \- invoke a procedure when there are no pending events
-.SH SYNOPSIS

-\fBTcl_DoWhenIdle\fR(\fIproc, clientData\fR)
-.sp
-\fBTcl_CancelIdleCall\fR(\fIproc, clientData\fR)

-Procedure to invoke.
-.AP ClientData clientData in
-Arbitrary one-word value to pass to \fIproc\fR.

-.SH DESCRIPTION
-.PP
-\fBTcl_DoWhenIdle\fR arranges for \fIproc\fR to be invoked
-when the application becomes idle.  The application is
-considered to be idle when \fBTcl_DoOneEvent\fR has been
-called, couldn't find any events to handle, and is about
-to go to sleep waiting for an event to occur.  At this
-point all pending \fBTcl_DoWhenIdle\fR handlers are
-invoked.  For each call to \fBTcl_DoWhenIdle\fR there will
-be a single call to \fIproc\fR;  after \fIproc\fR is
-invoked the handler is automatically removed.
-\fBTcl_DoWhenIdle\fR is only usable in programs that
-use \fBTcl_DoOneEvent\fR to dispatch events.
-.PP
-\fIProc\fR should have arguments and result that match the
-type \fBTcl_IdleProc\fR:
-.CS
-typedef void Tcl_IdleProc(ClientData \fIclientData\fR);
-.CE
-The \fIclientData\fR parameter to \fIproc\fR is a copy of the \fIclientData\fR
-argument given to \fBTcl_DoWhenIdle\fR.  Typically, \fIclientData\fR
-points to a data structure containing application-specific information about
-what \fIproc\fR should do.
-.PP
-\fBTcl_CancelIdleCall\fR
-may be used to cancel one or more previous
-calls to \fBTcl_DoWhenIdle\fR:  if there is a \fBTcl_DoWhenIdle\fR
-handler registered for \fIproc\fR and \fIclientData\fR, then it
-is removed without invoking it.  If there is more than one
-handler on the idle list that refers to \fIproc\fR and \fIclientData\fR,
-all of the handlers are removed.  If no existing handlers match
-\fIproc\fR and \fIclientData\fR then nothing happens.
-.PP
-\fBTcl_DoWhenIdle\fR is most useful in situations where
-(a) a piece of work will have to be done but (b) it's
-possible that something will happen in the near future
-that will change what has to be done or require something
-different to be done.  \fBTcl_DoWhenIdle\fR allows the
-actual work to be deferred until all pending events have
-been processed.  At this point the exact work to be done
-will presumably be known and it can be done exactly once.
-.PP
-For example, \fBTcl_DoWhenIdle\fR might be used by an editor
-to defer display updates until all pending commands have
-been processed.  Without this feature, redundant redisplays
-might occur in some situations, such as the processing of
-a command file.
-.SH BUGS
-.PP
-At present it is not safe for an idle callback to reschedule itself
-continuously.  This will interact badly with certain features of Tk
-that attempt to wait for all idle callbacks to complete.  If you would
-like for an idle callback to reschedule itself continuously, it is
-better to use a timer handler with a zero timeout period.
