SDL_VERSION
green
ie: SDL_VERSION (Macro)
Use this macro to determine the SDL version a/your program was compiled against.
Contents
Syntax
SDL_VERSION(x)
Function Parameters
x |
a pointer to an SDL_version struct to initialize |
Return Value
Fills the selected struct with:
(x)->major = SDL_MAJOR_VERSION
(x)->minor = SDL_MINOR_VERSION
(x)->patch = SDL_PATCHLEVEL
Code Examples
SDL_version compiled;
SDL_version linked;
SDL_VERSION(&compiled);
SDL_GetVersion(&linked);
printf("We compiled against SDL version %d.%d.%d ...\n",
compiled.major, compiled.minor, compiled.patch);
printf("But we are linking against SDL version %d.%d.%d.\n",
linked.major, linked.minor, linked.patch);
Remarks
This macro fills in an SDL_version structure with the version of the library you compiled against. This is determined by what header the compiler uses. Note that if you dynamically linked the library, you might have a slightly newer or older version at runtime. That version can be determined with SDL_GetVersion() which, unlike SDL_VERSION(), is not a macro.
??? This macro gathers information from SDL_MAJOR_VERSION, SDL_MINOR_VERSION, AND SDL_PATCHLEVEL (#defines) and fills the structure SDL_version with that information. ???
