Hello,

Is there anybody outthere who could supply me with some examples of
how I can setup a TimerIRQ Handler???
I use borlandC/C++ (3.1) and I have trouble using the SETVECT &
GETVECT functions.
If I do the same as shown in the example inside the helpfile I get the
following error message(s):

*error: can't convert (void)(interrupt near)*. to (void)(interrupt)*..
--> refered to setvect ... statements!
*error: call to non-function... -> refered to OldTimerIrq();

This is what I tried to do:

#define __CPPARGS
#define TIMERIRQnr  0x8

void interrupt (*OldTimerIrq)(__CPPARGS);

void interrupt NewTimerIrq(__CPPARGS)
{
	.....
	....
	OldTimerIrq();
}

void main()
{
	OldTimerIrq = getvect (TIMERIRQnr);
	setvect (TIMERIRQnr, NewTimerIrq);
	.....
	....
	setvect (TIMERIRQnr, OldTimerIrq);
}

What am I doing wrong, or is there someone who is kind enough to send
me a working source....????

Thanx for the help,
Simon
