1858 * Function: DSM_Entry, the only entry point into the Data Source Manager.
1859 *
1860 * Parameters:
1861 * pOrigin Identifies the source module of the message. This could
1862 * identify an Application, a Source, or the Source Manager.
1863 *
1864 * pDest Identifies the destination module for the message.
1865 * This could identify an application or a data source.
1866 * If this is NULL, the message goes to the Source Manager.
1867 *
1868 * DG The Data Group.
1869 * Example: DG_IMAGE.
1870 *
1871 * DAT The Data Attribute Type.
1872 * Example: DAT_IMAGEMEMXFER.
1873 *
1874 * MSG The message. Messages are interpreted by the destination module
1875 * with respect to the Data Group and the Data Attribute Type.
1876 * Example: MSG_GET.
1877 *
1878 * pData A pointer to the data structure or variable identified
1879 * by the Data Attribute Type.
1880 * Example: (TW_MEMREF)&ImageMemXfer
1881 * where ImageMemXfer is a TW_IMAGEMEMXFER structure.
1882 *
1883 * Returns:
1884 * ReturnCode
1885 * Example: TWRC_SUCCESS.
