FAX_ROUTE_CALLBACKROUTINES

The FAX_ROUTE_CALLBACKROUTINES structure contains pointers to callback functions the fax service provides. A fax routing extension's routing methods can call these callback functions to manage the files in the fax file list associated with a received fax document.

typedef struct _FAX_ROUTE_CALLBACKROUTINES {
    DWORD SizeOfStruct;  // structure size, in bytes
    PFAXROUTEADDFILE FaxRouteAddFile; 
               //pointer to callback that adds fax routing files
    PFAXROUTEDELETEFILE FaxRouteDeleteFile; 
               //pointer to callback that deletes fax routing files
    PFAXROUTEGETFILE FaxRouteGetFile; 
               //pointer to callback that retrieves routing file name
    PFAXROUTEENUMFILES FaxRouteEnumFiles; 
               //pointer to callback that enumerates routing files
    PFAXROUTEMODIFYROUTINGDATA FaxRouteModifyRoutingData;
               //pointer to callback that modifies routing data
} FAX_ROUTE_CALLBACKROUTINES, *PFAX_ROUTE_CALLBACKROUTINES; 

Members

SizeOfStruct

Specifies the size, in bytes, of the FAX_ROUTE_CALLBACKROUTINES structure. The fax service sets this member to sizeof(FAX_ROUTE_CALLBACKROUTINES). For information about backward compatibility, see the following Remarks section.

FaxRouteAddFile

Pointer to a FaxRouteAddFile callback function that a fax routing method uses to add a file to the fax file list associated with a received fax document.

FaxRouteDeleteFile

Pointer to a FaxRouteDeleteFile callback function that a fax routing method uses to delete a file from the fax file list associated with a received fax document.

FaxRouteGetFile

Pointer to a FaxRouteGetFile callback function that a fax routing method uses to retrieve a specific file name from the fax file list associated with a received fax document.

FaxRouteEnumFiles

Pointer to a FaxRouteEnumFiles callback function that a fax routing method uses to enumerate the files in the fax file list associated with a received fax document.

FaxRouteModifyRoutingData

Pointer to a FaxRouteModifyRoutingData callback function that a fax routing method uses to modify the routing data associated with a subsequent fax routing method.

Remarks

The fax routing extension DLL must store the pointers to these callback functions in a global variable for later use.

If the SizeofStruct member is greater than sizeof(FAX_ROUTE_CALLBACKROUTINES), this indicates that the FAX_ROUTE_CALLBACKROUTINES structure has been updated by Microsoft, and your application is using an earlier version. To maintain backward compatibility, changes will be appended to the original prototype of the FAX_ROUTE_CALLBACKROUTINES structure. For example, new members for additional callback functions will be added sequentially after the FaxRouteModifyRoutingData member.

For more information, see Fax Routing Extension Registration and Fax File Lists.
