In other words, let's say that library X is loaded using dlopen(), how can I get access to the path that was used to load the said library from within the library itself? Note that I cannot have the agent that loaded the library in the first place hand me this...
Hi there, I am developing a shared library using c++ under Linux. I would like to user log4cxx for logging purposes. However, I'm not sure how to initialize this.

(I am so missi...

When making a function call in Linux (or OS X for that matter), can the callee modify the values of the arguments on the stack? I was under the assumption that since the caller is the one that cleans them up, that they should contain the same values after the function call. However I found that GCC with -O2 was modifying parameters tha...
I've been using objdump to look at assembly code in Linux ELF binaries. Sometimes there is an indirect jump through a jump table that is stored in the rodata (read-only data) section.
