Function unpack_opaque_array

pub fn unpack_opaque_array<In: Read>(
    input: &mut In,
    bytes: &mut [u8],
    bytesz: usize,
) -> Result<usize>

Unpack a fixed-sized opaque array

Unpack a fixed-size array of raw bytes. The results are placed in bytes, but the actual wire-size of the array is bytesz. If the supplied bytes is too large, the remainer is filled in with 0x00; if it is too small, the excess elements are discarded.

All the bytes in bytes will be initialized after a successful call.
