Extracting DLL .def exported Function Names HOWTO

Extracting DLL .def exported Function Names HOWTO

Post by mlat » Thu, 26 Jul 2001 17:39:58



hi,
  I have been trying to write some code to extract the names of the
functions exported from a dll via the def file. (NOT USE the provided
utilities like the dependency walker)
Has anyone got ideas?.
I do not know the ordinal numbers, or have the .dbg file to use the
dbghelp functions.
thanks in advance

You will have to read .edata section of a dll.
Check Winnt.h file in /Include directory of Visual Studio.
Good description of NT Portable Executable File Format can be found in
<<The Portable Executable File Format from Top to Bottom>> article (MSDN).
And take a look at Exeview and Pefile SDK samples.

1. Calling a DLL from a DLL, exporting same functions/same function names?

Would it be possible to call a DLL (by using LoadLibrary) from a DLL,
and then export functions with the names as the imported functions from
the loaded DLL?

Is it possible to call a DLL (again by using LoadLibrary) from a DLL,
and export some of the functions?

Thanks,

Jan
