sdlGameControllerAddMappingsFromRw function

int sdlGameControllerAddMappingsFromRw(
  1. Pointer<SdlRWops> rw,
  2. int freerw
)

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

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.

\param rw the data stream for the mappings to be added \param freerw non-zero to close the stream after being read \returns the number of mappings added or -1 on error; call SDL_GetError() for more information.

\since This function is available since SDL 2.0.2.
