timeSetEvent is in the multimedia DLL WINMM.DLL. Here's where it gets fuzzy. Eventually, WINMM.DLL calls into KERNEL32.DLL. Eventually that calls into NTDLL.DLL. NTDLL issues the x86 instruction:
int 2Eh
Which is an interrupt. The debugger can't tell me where this tries to go; it never gets back. Anyone have any idea what this interrupt is?
That's the system trap interrupt (i.e., transition to ring 0 / kernel mode to perform a system call/service.) --sigbjorn
