1734	/**********************************************************************
1735	* Function: DSM_Entry, the only entry point into the Data Source Manager.
1736	*
1737	* Parameters:
1738	* pOrigin Identifies the source module of the message. This could
1739	* identify an Application, a Source, or the Source Manager.
1740	*
1741	* pDest Identifies the destination module for the message.
1742	* This could identify an application or a data source.
1743	* If this is NULL, the message goes to the Source Manager.
1744	*
1745	* DG The Data Group.
1746	* Example: DG_IMAGE.
1747	*
1748	* DAT The Data Attribute Type.
1749	* Example: DAT_IMAGEMEMXFER.
1750	*
1751	* MSG The message. Messages are interpreted by the destination module
1752	* with respect to the Data Group and the Data Attribute Type.
1753	* Example: MSG_GET.
1754	*
1755	* pData A pointer to the data structure or variable identified
1756	* by the Data Attribute Type.
1757	* Example: (TW_MEMREF)&ImageMemXfer
1758	* where ImageMemXfer is a TW_IMAGEMEMXFER structure.
1759	*
1760	* Returns:
1761	* ReturnCode
1762	* Example: TWRC_SUCCESS.
