SDL_AddGamepadMappingsFromIO - Man Page

#include <SDL3/SDL_gamepad.h>

int SDL_AddGamepadMappingsFromIO(SDL_IOStream *src, bool closeio);

You can call this function several times, if needed, to load different database files.

If a new mapping is loaded for an already known gamepad GUID, the later version will overwrite the one currently loaded.

Any new mappings for already plugged in controllers will generate SDL_EVENT_GAMEPAD_ADDED events.

Mappings not belonging to the current platform or with no platform field specified will be ignored (i.e. mappings for Linux will be ignored in Windows, etc).

This function will load the text database entirely in memory before processing it, so take this into consideration if you are in a memory constrained environment.

src

the data stream for the mappings to be added.

closeio

if true, calls SDL_CloseIO() on src before returning, even in the case of an error.

for more information.

It is safe to call this function from any thread.

This function is available since SDL 3.2.0.
