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 frame, using same parameters from previous frame. 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(). If pledgedSrcSize is not known at reset time, use macro ZSTD_CONTENTSIZE_UNKNOWN. If pledgedSrcSize > 0, its value must be correct, as it will be written in header, and controlled at the end. For the time being, pledgedSrcSize==0 is interpreted as “srcSize unknown” for compatibility with older programs, but it will change to mean “empty” in future version, so use macro ZSTD_CONTENTSIZE_UNKNOWN instead. @return : 0, or an error code (which can be tested using ZSTD_isError())
