WTSVirtualChannelWrite function
Writes data to the server end of a virtual channel.
Syntax
BOOL WTSVirtualChannelWrite( _In_ HANDLE hChannelHandle, _In_ PCHAR Buffer, _In_ ULONG Length, _Out_ PULONG pBytesWritten );
Parameters
- hChannelHandle [in]
-
Handle to a virtual channel opened by the WTSVirtualChannelOpen function.
- Buffer [in]
-
Pointer to a buffer containing the data to write to the virtual channel.
- Length [in]
-
Specifies the size, in bytes, of the data to write.
