know if .lib is static or import

I have .lib file compiled from C code. How I know if this self-contained static library or just an import lib and DLL will be needed at runtime? Is there some dumpbin option I'm missing?

Use the lib command. If it's static, lib will show you a pile of .obj files inside. Not so if it's an implib.

lib /list foo.lib

will do it.

Look in its accompanying header files ,if the function are 'decorated' with __declspec(dllimport) that it's an import library. Or look for an accompanying .def file ,that also tells you that it's an import library.
