I'm working on replacing some assembly code with C, and I'd like to redo
a timer-tick interrupt routine. In order to do this, I need to do a
stack switch. I know I can do this in Turbo C:
unsigned oldSS, oldSP, newSS, newSP;
void interrupt stackswitch(void)
{
disable();
oldSS = _SS;
oldSP = _SP;
_SS = newSS;
_SP = newSP;
}
How do I do the equivalent in Microsoft C 5.1? (_Must_ I use assembly?
How primitive! :-)
