[comp.sys.ibm.pc] Calling IBM C from Assembler interrupt routine

feldy@CS.UCLA.EDU (03/20/87)

I'm writing an interrupt routine on PC-AT and I want to call a C function from
the assembler code.  Does anyone have some "canned" code to set up the
stack and other pointers before calling the C routine? My current attempt
calls the C routine and then fails with a stack overflow.

I'm using Microsoft Assembler and IBM C version 1.0. This version of C is
roughly Microsoft C version 3.0 with "enhancements".

Thanks in advance.
