Hi Jeremy, > Does anyone know what would be the correct syntax in GCC would be for > #pragma pack(push, enter_pack_state)? Thanks a bunch. http://gcc.gnu.org/onlinedocs/gcc-4.1.1/gcc/Structure_002dPacking-Pragmas.ht ml I'm not sure if that syntax is supported on all platforms, or if it is just on Windows for MSVC compatibility. More often, the __attribute__((packed)) is suggested. HTH, --Eljay
