Virtual Channel SDK

Improve communications between your server and devices

A Citrix virtual channel is a bi-directional, reliable connection used for the exchange of generalized packet data between a Citrix host (XenApp or XenDesktop) and Citrix Receiver on end-user devices. 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 software engineers to write host-side applications and Citrix Receiver-side drivers to support additional virtual channels using the Citrix ICA protocol. The host-side virtual channel applications run on XenApp or XenDesktop, and the client-side portion of the virtual channel runs on the local device where Citrix Receiver resides. This SDK provides support for writing new virtual channels for the Win32, Linux and Mac OSX versions of Citrix Receiver. See the accompanying documentation for detailed information about the client versions supported.
