   240 /* SDL stdinc inline functions:
   241 
   242    The theory here is that, by default, we forcibly inline what we can--with
   243    real inline functions that avoid macro side-effects--and your app will use
   244    the inline version by default. However, we expose a non-inline version
   245    too, which internally just wraps the inline version in a real function,
   246    so the symbol is always available in the library even if your app
   247    bypassed it with the inline version. The SDL_*_inline versions aren't
   248    guaranteed to exist, so never call them directly; use SDL_* instead,
   249    and trust the system to give you the right thing.
   250 
   251    The benefit here is that you can dlsym() these functions, which you
   252    couldn't if you had macros, you can link against a foreign build of SDL
   253    even if you configured differently, and you can drop the unconfigured SDL
   254    headers into a project without #defining HAVE_MALLOC (etc) and still link.
