Looks like the VIX API, version 10.2, reads /etc/vmware/config, /usr/lib/vmware/config, and $HOME/vmware/config, to read the vix.libdir key. This is on Linux, obviously.
Then it uses the vix.libdir key to find the location of the vixwrapper-config.txt, followed by the location of the libraries specific to the specific vmware product.
It would be really nice to have an api that I could call at the beginning of my program to tell VIX where its config files are.
Please & thanks!
