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())
