I am stock and I don't know what to do next. I can't find those headers on my Centos 5 Linux. Plus, I don't know the equivalence of those above headers for Linux. I know I have to add an If statement for Solaris and Linux for the include headers, and I don't know which headers will be included on the if/else statement.
