Discussion

The SSLWrite(_:_:_:_:) function might call the SSLWriteFunc function that you provide (see SSLSetIOFuncs(_:_:_:)). Because you may configure the underlying connection to operate in a no-blocking manner, a write operation might return errSSLWouldBlock, indicating that less data than requested was actually transferred. In this case, you should repeat the call to SSLWrite(_:_:_:_:) until some other result is returned.
