3.2.5.2.2 Handling Redirection Surfaces Lifetime Management Order

  • Article

Upon receipt of the TS_COMPDESK_SURFOBJ message, the surface manager proxy tests the highest bit of the message's cacheId field. The surface manager proxy processes the message as follows:

  • If the highest bit is NOT set, the surface manager proxy creates the redirection surface using the supplied cacheId identified.

  • If the highest bit is set, the surface manager proxy destroys the redirection surface that the supplied cacheId identified.

  • The hSurf field is a unique identifier used to identify the redirection surface generated on the server.

  • The surfaceBpp, cx, and cy fields are used to create a redirection bitmap on the client.
