If you are writing a DLL and need to know the detailed information about your compiled library, check out Dependency Walker. From their website:
Dependency Walker is a free utility that scans any 32-bit or 64-bit Windows module (exe, dll, ocx, sys, etc.) and builds a hierarchical tree diagram of all dependent modules. For each module found, it lists all the functions that are exported by that module, and which of those functions are actually being called by other modules.
In addition to a GUI product, MS Visual Studio provides
dumpbin. Dumpbin will
dump the contents of a binary file. For DLLs, the following command is useful:
dumpbin /exports SomeFile.dll. Dumpbin is easily accessed through the Visual
Studio Command Prompt found under the Tools menu in VS or in the VS start menu
folder under “Visual Studio Tools.” Sample output with /exports option ran on a
simple DLL I created the other day.
