+ version 1.5, June 1993. Specification Update 1.5
+ Change DC to TW
+ Change filename from DC.H to TWAIN.H
+ version 1.5, July 1993. Remove spaces from country identifiers
+
+ version 1.7, July 1997 Added Capabilities and data structure for
+ document imaging and digital cameras.
+ KHL.
+ version 1.7, July 1997 Inserted Borland compatibile structure packing
+ directives provided by Mentor. JMH
+ version 1.7, Aug 1997 Expanded file tabs to spaces.

+ * Function: DSM_Entry, the only entry point into the Data Source Manager.
+ *
+ * Parameters:
+ * pOrigin Identifies the source module of the message. This could
+ * identify an Application, a Source, or the Source Manager.
+ *
+ * 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:
+ * ReturnCode
+ * Example: TWRC_SUCCESS.
