    Listing ProcName in a DLL

    How do I get the names of all the functions within a DLL? Microsoft's "Depends" application does it, so I know it's possible.

    You need to know the file format for the dll. It is called Portable Executable format ( PE in short ). The exports of a dll are kept in a table called the export table. And there is a specific structure. Please google for "PE format" and you should be able to find resources. There is an article by Matt pietrek which is a good read.

    Yup, Kirants is right on the mark, as usual...

    It was one of my favorite articles from one of my favorite authors - Matt P

    Here is the source code for his version of depends.

    Hope this helps.

    You can also use DUMPBIN or Link utility without knowing anything about specific formats or protocols.
    Creating process for running hidden DUMPBIN and redirecting it to a pipe would allow retrieving information about exports and more by reading pipe buffer and parsing strings.
