Overview
A Citrix Independent Computing Architecture (ICA) virtual channel is a bi-directional error-free connection used for the exchange of generalized packet data between a Citrix Presentation Server and a Citrix ICA Client. Virtual channels are the primary mechanism used by Citrix to pass a variety of information between a client and server application. For example, sound, graphics, client drive mapping, and printing are just a few of the virtual channels written by Citrix.
The Citrix Virtual Channel Software Development Kit (VCSDK) allows you to write both server-side applications and client-side drivers to support additional virtual channels using the Citrix ICA protocol. The server-side virtual channel applications run on Citrix Presentation Servers and the client application runs on the local device where the Citrix ICA client resides. This SDK provides support for writing new virtual channels for the Citrix Win32 and Windows CE ICA clients. See the accompanying documentation for detailed information about the client versions supported.
