inportb, outportb functions

QNX DEVELOPERS General Programming

Hi,

I’m trying to program a pcm IO card. I have some DOS examples which are using the inportb and outportb functions to write/read. For example:

outportb( base + 3 , 0x0 ); // disable all gates

The first parameter is the adress, second is the value. But… what are these IO functions in QNX?

Greetings,
Rick

in8 and out8. Also look at mmap_device_io() and ThreadCtl()
