3. Tikslas ir kas naudoja
Windows Desktop Sharing is used by software developers to create applications that use multiple-party screen-sharing technology. Key scenarios include remote assistance, real-time collaboration and conferencing, and video communication. With Remote Desktop Services, a session is always created when a user connects remotely through Remote Desktop Protocol (RDP). With Windows Desktop Sharing, a local desktop can be transmitted over an RDP connection without creating an additional session.
Windows Desktop Sharing is designed for use by developers of applications that incorporate screen sharing functionality.

5. RDPSRAPI_WND_FLAGS enumeration
Defines values for the type of window. These flags can be retrieved from the IRDPSRAPIWindow interface that represents each Win32 window.
The list of windows on the sharing user session can be retrieved on both the sharer and the viewer through the IRDPSRAPIApplicationFilter interface by calling the get_Windows method.

typedef enum {
CHANNEL_FLAGS_LEGACY        = 0x01,
CHANNEL_FLAGS_UNCOMPRESSED  = 0x02
} CHANNEL_FLAGS;
CHANNEL_FLAGS_LEGACY
Reserved.
CHANNEL_FLAGS_UNCOMPRESSED
Data sent on the channel is not compressed. Use this option if the data is already compressed.
