How would you list the available functions etc contained within a compiled library?
For ELF binaries, you can use readelf:
readelf -sW a.out | awk '$4 == "FUNC"' | c++filt
-s: list symbols
-W: don't cut too long names
The awk command will then filter out all functions, and c++filt will unmangle them. That means it will convert them from an internal naming scheme so they are displayed in human readable form. It outputs names similar to this (taken from boost.filesystem lib):
285: 0000bef0 91 FUNC WEAK DEFAULT 11 boost::exception::~exception()
Without c++filt, the name is displayed as
For Microsoft tools, "
link /dump /symbols <filename>" will give you the gory details. There are probably other ways (or options) to give an easier to read listing.
Under Linux/Unix you can use
objdump -T to list the exported symbols contained in a given object. Under Windows there's
dumpbin /exports). Note that C++ function names are mangled in order to allow overloads.
EDIT: after seeing codelogic's anwser I remembered that objdump also understands -C to perform de-mangling.
use this command:
objdump -t "your-library"
It will print more than you want - not just function names, but the entire symbol table. Check the various attributes of the symbols you get, and you will be able to sort out the functions from variables and stuff.
