Expand description

ZSTD_getFrameHeader() : decode Frame Header into zfhPtr, or requires larger srcSize. @return : 0 => header is complete, zfhPtr is correctly filled, >0 => srcSize is too small, @return value is the wanted srcSize amount, zfhPtr is not filled, or an error code, which can be tested using ZSTD_isError()
