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