SDL_VERSIONNUM

This macro turns the version numbers into a numeric value:

Header File

Defined in SDL_version.h

Syntax

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

Remarks

(1,2,3) -> (1203)

This assumes that there will never be more than 100 patchlevels.

In versions higher than 2.9.0, the minor version overflows into the thousands digit: for example, 2.23.0 is encoded as 4300, and 2.255.99 would be encoded as 25799.

This macro will not be available in SDL 3.x.
