HRESULT GetSessionDesc(LPVOID lpData,
LPDWORD lpdwDataSize);
Retrieves the properties of the current open session.
·Returns DP_OK if successful, or one of the following error values otherwise:
lpData
Address of a buffer where the session description data is to be written. Set this parameter to NULL to request only the size of data. The lpdwDataSize parameter will be set to the size required to hold the data.
lpdwDataSize
Address of a variable that is initialized to the size of the buffer before calling this method. After the method returns, this parameter will be set to the size, in bytes, of the group data. If the buffer was too small (DPERR_BUFFERTOOSMALL), then this parameter will be set to the buffer size required.
After this method returns, the pointer lpData should be cast to the DPSESSIONDESC2 structure to read the session description data.
