/* SDL stdinc inline functions:

   The theory here is that by default we forcibly inline what we can, and your
slouken@7005
   239
   app will use the inline version by default. However we expose a non-inline
slouken@7005
   240
   version too, so the symbol is always available in the library even if your app
slouken@7005
   241
   bypassed the inline version. The SDL_*_inline versions aren't guaranteed to
slouken@7005
   242
   exist, so never call them directly; use SDL_* instead, and trust the system
slouken@7005
   243
   to give you the right thing.
icculus@7003
   244
icculus@7003
   245
   The benefit here is that you can dlsym() these functions, which you
icculus@7003
   246
   couldn't if you had macros, you can link against a foreign build of SDL
icculus@7003
   247
   even if you configured differently, and you can drop the unconfigured SDL
icculus@7003
   248
   headers into a project without #defining HAVE_MALLOC (etc) and still link.
