list library function of a shared library .so

powah · 04-25-2006, 11:10 AM

I like to find out what functions of a shared library xxx.so has (i.e. list the function names and parameters). How to do that?

You can use
nm -Ca /lib/mylib.so.1
man nm for full

But I doubt you will find the parameters of the functions. You would need to inspect the asm code and look at how the stack moves. It would tell you the size of the parameters, not the type which has no meaning in an object file

You can see the parameters by reading the man page(s) (or the src). They are not in the library.

For the shared libs:

Code:

nm -D /lib/mylib.so.1

Hi,
I'm too facing the same problem now.
Did u get any solution for this.

@kamatchisl.

The three usual tools can be used for objects : nm, objdump, readelf.

Random examples ...

readelf -s /usr/lib/lib<example>.so.XX.x | grep <OBJECT_abc>
objdump -Dslx /lib/libcap.so.2 | more
objdump -x /path/to/file/filename | head -50

Functions / parameters , see post 2-3-4

..

But through the commands i could get only the method names not the return type
Could anyone help me on getting the return type of method inside library

Not being a programmer, I don't know what you mean by "return".
( You may have to read the source code for the library ? ).
