It's possible to call a function from a DLL file without knowing about function prototype ? I try to extract all exported function from a DLL file using pe-parser library, But i only have the function name and i don't know about function input/output. Is there any solution to find exported function input/output from dll files ? or call functions without knowing about function prototype ?
TL;DR - No.
In order to call the function properly, you need to know the function prototype. It is usually provided in an h file that ships with the DLL.
You can try to reverse-engineer the DLL in order to figure out the prototype but this information is not a part of the PE file.
If you have a PDB file you can extract the relevant information from it. See this answer.
