NAME: BLT_MASTER_TIMER
|
|
|
|
SYNOPSIS: Master timer. It consists of a set of function to
|
|
control the list of timer.
|
|
|
|
INTERFACE: Init() - initialize the master timer
|
|
Term() - terminate the master timer
|
|
|
|
ResetIterator() - reset the link list to the first timer
|
|
NextTimer() - return the next timer in the link list.
|
|
RemoveTimer() - remove the given timer from the link list
|
|
Insert() - insert the given timer to the link list
|
|
by using insertion method.
|
|
ClearMasterHotkey() - clears hotkey (if any) associated
|
|
with invisible master timer window
|
|
and returns vkey code (NULL if none).
|
|
|
|
PARENT: BASE
|
|
|
|
USES: SLIST, ITER, TIMER_BASE
|
|
|
|
CAVEATS: In order to use the package, the programmer should called
|
|
BLT_MASTER_TIMER's Init function. He/she should also called
|
|
the Term function at the end of the application.

terryk 18-Jul-91 Change the name of the functions
|
|
to ResetIterator and NextTimer
|
|

|
|
use of it

NOTES: CODEWORK. The DISPATCHER::OnTimer method should be

disambiguate it from this method. Perhaps this method

could also get a better name.

Note, don't confuse the OnTimerNotification method with

the DISPATCHER::OnTimer method.
