// The following ifdef block is the standard way of creating macros which make exporting

// symbol defined on the command line. this symbol should not be defined on any project
// that uses this DLL. This way any other project whose source files include this file see
// FEXTRACKER_API functions as being imported from a DLL, wheras this DLL sees symbols
