Function zstd_sys::ZSTD_resetCStream

pub unsafe extern "C" fn ZSTD_resetCStream(
    zcs: *mut ZSTD_CStream, 
    pledgedSrcSize: c_ulonglong
) -> usize

ZSTD_resetCStream() : start a new compression job, using same parameters from previous job. This is typically useful to skip dictionary loading stage, since it will re-use it in-place.. Note that zcs must be init at least once before using ZSTD_resetCStream(). pledgedSrcSize==0 means "srcSize unknown". If pledgedSrcSize > 0, its value must be correct, as it will be written in header, and controlled at the end. @return : 0, or an error code (which can be tested using ZSTD_isError())
