Advice needed from C gurus for an external project

[jbv]

Hi list,

What is the best place (website, dev. forum, mailing
list...) to look for C librairies to include or adapt in an
external to access a PCI board (both on Mac & PC) ?

The tasks should remain rather simple :
- locating the board on the PCI bus
- sending raw data to the board
- receiving confirmation from the board.

The PCI board already exists. The idea is to evaluate
the possibility to use REv to build a UI to communicate /
configure it...

Thanks,
JB
