3.1.1 TTF_Linked_Version

const SDL_version *TTF_Linked_Version()
void TTF_VERSION(SDL_version *compile_version)

This works similar to SDL_Linked_Version and SDL_VERSION.
Using these you can compare the runtime version to the version that you compiled with.

SDL_version compile_version, *link_version; TTF_VERSION(&compile_version); printf("compiled with SDL_ttf version: %d.%d.%d\n", compile_version.major, compile_version.minor, compile_version.patch); link_version=TTF_Linked_Version(); printf("running with SDL_ttf version: %d.%d.%d\n", link_version->major, link_version->minor, link_version->patch);
