// These are (mostly) the same symbols as BSD sockets, so to prevent conflicts
//  with the _actual_ C runtime on the host, we name them OS2_*. The LX
//  loader exports them with the correct names. If you're recompiling an
//  OS/2 app and using this for API support, just use real BSD sockets
//  instead.

// !!! FIXME: lots of "int" and such in here that should probably be int32, etc.
