## page was renamed from SDL_GameControllerAddMappingsFromFile #pragma section-numbers off #pragma camelcase off || DRAFT|| ##*^*^*^*^*See http://wiki.libsdl.org/moin.cgi/SGFunctions for details on editing this page*^*^*^*^* = SDL_GameControllerAddMappingsFromRW = Use this function to load a set of [[CategoryGameController|Game Controller]] mappings from a seekable SDL data stream (memory or file), filtered by the current [[SDL_GetPlatform]](). A community sourced database of controllers is available [[https://raw.github.com/gabomdq/SDL_GameControllerDB/master/gamecontrollerdb.txt|here|target="_blank"]] (on !GitHub). <> == Syntax == {{{#!highlight cpp 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. == Code Examples == {{{#!highlight cpp SDL_GameControllerAddMappingsFromRW(SDL_RWFromFile("gamecontrollerdb.txt", "rb"), 1); }}} == 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. == Related Functions == .[[SDL_GameControllerAddMapping]] .[[SDL_GameControllerAddMappingsFromFile]] .[[SDL_GameControllerMappingForGUID]] ---- [[CategoryAPI]], [[CategoryGameController]]
