Linux Question

How do I view the list of functions a Linux shared library is exporting?

I want to view the exported functions of a shared library on Linux.

What command allows me to do this?

(On Windows I use the program depends)


What you need is nm and its -D option:

$ nm -D /usr/lib/libopenal.so.1
00012ea0 T alcSetThreadContext
000140f0 T alcSuspendContext
         U atanf
         U calloc

Exported sumbols are indicated by a T. Required symbols that must be loaded from other shared objects have a U. Note that the symbol table does not include just functions, but exported variables as well.

See the nm manual page for more information.
