Function zstd_sys::ZSTD_readSkippableFrame

pub unsafe extern "C" fn ZSTD_readSkippableFrame(
    dst: *mut c_void,
    dstCapacity: usize,
    magicVariant: *mut c_uint,
    src: *const c_void,
    srcSize: usize
) -> usize

ZSTD_readSkippableFrame() : Retrieves a zstd skippable frame containing data given by src, and writes it to dst buffer.

The parameter magicVariant will receive the magicVariant that was supplied when the frame was written, i.e. magicNumber - ZSTD_MAGIC_SKIPPABLE_START. This can be NULL if the caller is not interested in the magicVariant.

Returns an error if destination buffer is not large enough, or if the frame is not skippable.

@return : number of bytes written or a ZSTD error.
