Accessing Extension Configuration Data

A fax extension DLL can access its global and device-specific extension configuration data from within the fax server process (internal access). Processes that execute outside of the fax server process can also access configuration data (external access).

• Internal access. Fax routing extension DLLs and fax service providers (FSPs) can access their configuration data by calling the fax service callback functions FaxExtGetData and FaxExtSetData to retrieve and set configuration data. Note that the extension DLL must export the FaxExtInitializeConfig function. For more information, see Fax Service and Configuration Extension Interaction.
