Detailed Description

This header defines the current SDL version

Define Documentation

#define SDL_COMPILEDVERSION   SDL_VERSIONNUM(SDL_MAJOR_VERSION, SDL_MINOR_VERSION, SDL_PATCHLEVEL)

This is the version number macro for the current SDL version

#define SDL_VERSION

(

X

)

Value:

{                                                                       \
        (X)->major = SDL_MAJOR_VERSION;                                 \
        (X)->minor = SDL_MINOR_VERSION;                                 \
        (X)->patch = SDL_PATCHLEVEL;                                    \
}

This macro can be used to fill a version structure with the compile-time version of the SDL library.

#define SDL_VERSION_ATLEAST	(	X,
		Y,
		Z		)	(SDL_COMPILEDVERSION >= SDL_VERSIONNUM(X, Y, Z))

This macro will evaluate to true if compiled with SDL at least X.Y.Z

#define SDL_VERSIONNUM	(	X,
		Y,
		Z		)	((X)*1000 + (Y)*100 + (Z))

This macro turns the version numbers into a numeric value: (1,2,3) -> (1203) This assumes that there will never be more than 100 patchlevels

Function Documentation

DECLSPEC const SDL_version* SDLCALL SDL_Linked_Version

(

void

)

This function gets the version of the dynamically linked SDL library. it should NOT be used to fill a version structure, instead you should use the SDL_Version() macro.
