I/O Function Questions

Post by tie hu » Mon Jun 10, 2002 5:22 pm

1)Does anyone know how to use in8() and out8() in qnx?
2)Can I use these functions to read and write
data from I/O port?
3)In QNX 6.2 library,
uint8_t in8(uintptr_t port);
what 's the meaning of unintptr and uint8_t?
4)Is in8() and out() same with _inp() and
_outp() function in Visual C++?
