How to export the functions supported by teh TSP

[Mohit]

Hi friends,

Can any one tell me when and how a TSP can export the supported functions?

I mean, do the TSP export the supported TSPI functions immediately after
service provider installation by it self or the TAPISRV will query the
supported TSPI functions to TSP after instalaltion?

Thanks,
Mohit

Mohit,
one way is the usage of a .DEF file,
another ways the usage of the dllexport attribute.
Please see MSDN for details.

Exported functions of a DLL (and hence a TSP) are static.
The function entry points are ceated during the compilation / link process
in Visual Studio.
You can use MS Dependeny Walker (a tool part of VS) to explore a DLL's
exported functions.

After a process (e.g. TAPISRV) has loaded a DLL/TSP dynamically
(LoadLibrary()) it can use GetProcAddress() to retrieve the function entry
point for a know ProcName.
Please see MSDN for details.
