Controls how the size of the RIFF chunk affects the loading of a WAVE file.
Defined in SDL_hints.h, but apps should only #include "SDL.h"!
#define SDL_HINT_WAVE_RIFF_CHUNK_SIZE "SDL_WAVE_RIFF_CHUNK_SIZE"The size of the RIFF chunk (which includes all the sub-chunks of the WAVE file) is not always reliable. In case the size is wrong, it's possible to just ignore it and step through the chunks until a fixed limit is reached.
Note that files that have trailing data unrelated to the WAVE file or corrupt files may slow down the loading process without a reliable boundary. By default, SDL stops after 10000 chunks to prevent wasting time. Use the environment variable SDL_WAVE_CHUNK_LIMIT to adjust this value.
This variable can be set to the following values:
"force" - Always use the RIFF chunk size as a boundary for the chunk search "ignorezero" - Like "force", but a zero size searches up to 4 GiB (default) "ignore" - Ignore the RIFF chunk size and always search up to 4 GiB "maximum" - Search for chunks until the end of file (not recommended)
