I am writing a tutorial and creating a wrapper on streaming compression. In
the code, I setup the stream source pointer: (input is of type Data)
// set up the stream with the input source
input.withUnsafeBytes { (bytes: UnsafePointer<UInt8>) in
stream.src_ptr = bytes
}
stream.src_size = input.count
Input is guaranteed to be alive for the entire lifetime of the stream.
Everything seems to work fine but I thought I remember reading somewhere that
it is bad form to let the bytes escape out of the withUnsafeBytes closure.
Anyone know if I'm I dipping into undefined behavior here?
Thanks in advanced,
Ray
