Use this macro to convert separate version components into a single numeric value.
SDL_VERSIONNUM(X, Y, Z)
X |
major version; reported in thousands place |
Y |
minor version; reported in hundreds place |
Z |
update version (patchlevel); reported in tens and ones places |
This assumes that there will never be more than 100 patchlevels.
Example:
```SDL_VERSIONNUM(1,2,3) -> (1203)```
