For instance:

void* sdl_library = dlopen("libSDL.so", RTLD_LAZY);
void* initializer = dlsym(sdl_library,"SDL_Init");

Assuming no errors, initializer will point to the function SD_Init in the shared library libSDK.so.

However this requires knowing the symbol "SDL_Init" exists.

Is it possibly to query a library for all its symbols? Eg, in this case it would return SDL_Init, the function pointer, and any other symbols exported by libSDL.so.

I've taken a library that is distributed as a binary lib (.a) and header, written some c++ code against it, and want to wrap the results up in a python module. I've done this here. The problem is that when importing this module on Mac OSX (I've tried 10.5 and 10.6), I get the following error: dlopen(/Library/Python/2… >>> More

I have an application which can make use of plugins which are loaded at runtime using dlopen. Each of the plugins defines a function toretrieve the plugin information which is defined using a common structure.

I have a library of dubious origins which is identified by file as a 32 bit executable. However, when I try to dlopen it on a 32 bit CentOS 4.4 machine, dlopen terminates with SIGFPE. Surely if there was something wrong with the format of the binary then dlopen should be handling an error? So the… >>> More

My program uses plugins, that are loaded dynamically with dlopen(). The locations of these plugins can be arbitrary, so they aren't necessarily in the library path. In some cases, one plugin needs to depend on another plugin. So if A and B are dynamic libraries, I'll first load A, then load B which… >>> More

My Linux application (A) links against a Third Party shared Library (B) which I don't have source code to. This library makes use of another third party shared library that I don't have source code to (C). I believe that (B) uses dlopen to access (C) instead of directly linking. My reasoning for this… >>> More
