/* vgmstream's public API
*
* By default vgmstream behaves like a simple decoder (extract samples until stream end), but you can configure it
* to loop N times or even downmix. In other words, it also behaves a bit like a player.
*
* It exposes multiple options and convenience functions beyond simple decoding mainly for various plugins,
* since it was faster moving shared behavior to core rather than reimplementing every time.
*
* All this may make the API a bit twisted and coupled (sorry, tried my best), probably will improve later. Probably.
*
* Notes:
* - vgmstream may dynamically allocate stuff as needed (not too much beyond some setup buffers, but varies per format)
* - previously the only way to use vgmstream was accesing its internals. Now there is an API internals may change in the future
* - some details described in the API may not happen at the moment (they are defined for future internal changes)
* - main reason it uses the slighly long-winded libvgmstream_* names is that internals use the vgmstream_* 'namespace'
* - c-strings should be in UTF-8
* - the API is still WIP and may be slightly buggy overall due to lack of time, to be improved later
* - vgmstream's features are mostly stable, but this API may be tweaked from time to time (check API_VERSION)
*
* Basic usage (also see api_example.c):
* - libvgmstream_init(...) // base context
* - libvgmstream_setup(...) // config if needed
* - libvgmstream_open(...) // setup format
* - libvgmstream_play(...) // main decode
* - output samples + repeat libvgmstream_play until stream is done
* - libvgmstream_free(...) // cleanup
