/**
 * The server-side virtual channel API follows the Microsoft Remote Desktop
 * Services API functions WTSVirtualChannel* defined in:

 *
 * Difference between the MS API are documented in this header. All functions
 * are implemented in and integrated with libfreerdp-channels.
 *
 * Unlike MS API, all functions except WTSVirtualChannelOpenEx in this
 * implementation are thread-safe.
