Define
#define LIBTEST_PAL_STDLIB_CALLBACK_CALLING_CONVENTION [calling convention]
Example
#if( defined _WIN32 && define KERNEL_BUILD && defined _M_IX86 ) // TRD : bloody x86 on MSVC... #define LIBTEST_PAL_STDLIB_CALLBACK_CALLING_CONVENTION __cdecl #endif
Optionality
This define is mandatory and the library cannot compile if in the cases where it is needed, it is not set. If the define is not required, it must be defined as empty, rather than omitted.
Notes
Winner of "World's Most Annoying Abstraction Define" award.
