c++ - Is there a .def file equivalent on Linux for controlling exported function names in a shared library? -


I am creating a shared library at Ubuntu 9.10. I want to export a subset of my works only from the library. On the Windows platform, this will be done using a module definition ( .def ) file that lists the external and internal names of the jobs exported from the library.

I have the following questions:

  1. How can I restrict the exported functions of shared libraries to those people (such as .def file equivalent)

  2. Using .def files as an example, you can assign a function to an external name different from its internal name (useful to prevent name collisions and disturbances Re-aligning names etc)

  3. In the window I have export command (I Vaccine) would be able to check the list of using export functions and addresses, a common way to do this on Linux what?

Only the few symbols in the shared object on Linux appear to be the most The common way is to - visibility = hidden for GCC and then to decorate those symbols you want __ attribute __ ((visibility ("default")) . < / P>

If you look for an export file like solution, you can type the linker option --reven-symbols-file = FILENAME whatever you like.

I do not know an easy way to export a function with a different name from my function name, but possibly with an ELF editor. Edit: I think You can use the Linker script (take a look at the man page for the link) to assign the value to the symbols in the link phase, so give an alternate name for a given function. You have also not tried to do this.

You can use the readelf command to see the symbols in the shared object. readelf -Ds If I remember correctly.
