int 0F2h   
Hello,

Can anyone tell me (or tell me what documentation to examine) to find
out exactly what the "int 0F2h" (with al=0,1,2, & 0Ch) does in the
QNX 4.25 OS?
I was running some released code in the debugger and ran across these assembly language instructions.

Thanks,
Dan

/usr/include/sys/kernel.h should answer all your questions.

No worries, the more the merrier.

Under QNX4 a kernel call uses this instruction to enter the kernel.

Hope this helps.
