SDL_GameControllerAddMappingsFromRW

Load a set of Game Controller mappings from a seekable SDL data stream.

Syntax

int SDL_GameControllerAddMappingsFromRW(SDL_RWops * rw, int freerw);

Function Parameters

rw

the data stream for the mappings to be added

freerw

non-zero to close the stream after being read

Return Value

Returns the number of mappings added or -1 on error; call SDL_GetError() for more information.

Remarks

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

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

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.

Version

This function is available since SDL 2.0.2.

Code Examples

SDL_GameControllerAddMappingsFromRW(SDL_RWFromFile("gamecontrollerdb.txt", "rb"), 1);
SDL_GameControllerAddMapping
SDL_GameControllerAddMappingsFromFile
SDL_GameControllerMappingForGUID
