Edit Question
Title
Body
I'm looking for a way to reliably determine whether C++ code is being compiled in 32 vs 64 bit. We've come up with what we think is a reasonable solution using macros, but was curious to know if people could think of cases where this might fail or if there is a better way to do this. Please note we are trying to do this in a cross-platform, multiple compiler environment. #if ((ULONG_MAX) == (UINT_MAX)) # define IS32BIT #else # define IS64BIT #endif #ifdef IS64BIT DoMy64BitOperation() #else DoMy32BitOperation() #endif Thanks.
