Function SDL_GetRevision

pub unsafe extern "C" fn SDL_GetRevision() -> *const i8
Available on crate feature dep_sdl3 only.
Expand description

Get the code revision of SDL that is linked against your program.

This value is the revision of the code you are linked with and may be different from the code you are compiling with, which is found in the constant [SDL_REVISION].

The revision is arbitrary string (a hash value) uniquely identifying the exact revision of the SDL library in use, and is only useful in comparing against other revisions. It is NOT an incrementing number.

If SDL wasn’t built from a git repository with the appropriate tools, this will return an empty string.

You shouldn’t use this function for anything but logging it for debugging purposes. The string is not intended to be reliable in any way.

§Return value

Returns an arbitrary string, uniquely identifying the exact revision of the SDL library in use.

§Availability

This function is available since SDL 3.2.0.
