Find out what functions a static C library has

Question

I have a static C library (say mylib.a) and I was wondering if it's possible to find out what functions are implemented inside that file. I don't have a corresponding header file. what I need is like the equivalent of javap for Java.

On Windows you can use dumpbin. On Linux and friends you can use nm.

nm works with both dynamic (libfoo.so) and static (libbar.a) libraries – Kemin Zhou Jan 07 '17 at 07:40

Use nm. That will only give you the symbol names - of which most of the symbols prefixed with T will be functions. Function arguments are not retained in the binary.
