* Function: DSM_Entry, the only entry point into the Data Source Manager.

* Parameters:
* pOrigin Identifies the source module of the message. This could

*
* pDest Identifies the destination module for the message.
* This could identify an application or a data source.
* If this is NULL, the message goes to the Source Manager.
*
* DG The Data Group.
* Example: DG_IMAGE.
*
* DAT The Data Attribute Type.
* Example: DAT_IMAGEMEMXFER.
*
* MSG The message. Messages are interpreted by the destination module
* with respect to the Data Group and the Data Attribute Type.
* Example: MSG_GET.
*
* pData A pointer to the data structure or variable identified
* by the Data Attribute Type.
* Example: (TW_MEMREF)&ImageMemXfer
* where ImageMemXfer is a TW_IMAGEMEMXFER structure.
*
* Returns:
