[comp.sys.ibm.pc] MSC interrupts

mac@uvacs.UUCP (Alex Colvin) (11/12/86)

Does MicroSoft "C" (v4.0) have the necessary hooks for writing device
interrupt handlers?  There is a Signal handler. but the manual mentions
only two signals, SIGINT and SIGFPE.  What I'm looking for is the ability
to call my C code on IRQn and clock rupts.

Datalight C provides library routines to intercept any interrupt, and
cause a specified C function to be executed. The return code from the C
function can be used to specify whether the previous vector can be
'chained' to or not. Source code is provided for the library routines,
I imagine they could be easily adapted to MSC.

Datalight C is $99 and available from (206) 367-1803.
