- I am trying to port a Linux program to ESIX SVR4.0.3a. The program is
- tvgalib which is a library for SVGA mode on a Trident 8900C.
- Naturally, tvgalib writes directly to io ports using inb & outb; in the
- Linux source, initial access to each port is preceded by a call to
- ioperm() which apparently grants permission to write to the port.
-
- I cannot find any reference to ioperm() on my system, and I don't know how
- this should be done in SVR4. Can anyone enlighten me?
