// Purpose:       POSIX export header
// Description:   This header contains definitions that the POSIX package exports
//                to other packages. These are generally interfaces that are not
//                provided by the public API.
//                
//              
// Usage:
//              #ifdef CYGPKG_POSIX
//              #include <export.h>
//              #endif
//              ...
//
