/**
Streaming compression, bufferless mode
A ZSTD_CCtx object is required to track streaming operations.
Use ZSTD_createCCtx() / ZSTD_freeCCtx() to manage it.
A ZSTD_CCtx object can be re-used multiple times.
First operation is to start a new frame.
Use ZSTD_compressBegin().
You may also prefer the advanced derivative ZSTD_compressBegin_advanced(), for finer parameter control.
Then, consume your input using ZSTD_compressContinue().
The interface is synchronous, so all input will be consumed.
You must ensure there is enough space in destination buffer to store compressed data under worst case scenario.
Worst case evaluation is provided by ZSTD_compressBound().
Finish a frame with ZSTD_compressEnd(), which will write the epilogue.
Without it, the frame will be considered incomplete by decoders.
You can then re-use ZSTD_CCtx to compress new frames.
