SDL_IN_BYTECAP - Macro that annotates function params with input buffer size.

       This macro is available since SDL 3.2.0.

Simple Directmedia Layer                           SDL 3.2.10                                  SDL_IN_BYTECAP(3)

       If we were to annotate memcpy :

              void *memcpy(void *dst, SDL_IN_BYTECAP(len) const void *src, size_t len);

       This  notes  that src should be len bytes in size and is only read by the function. The compiler or other
       analysis tools can warn when this doesn't appear to be the case.

       On compilers without this annotation mechanism, this is defined to nothing.

       Defined in SDL3/SDL_stdinc.h
