How to find the path of the DLL which is under execution in linux?
In windows,it can be done by GetModuleFileName() function.
Tried with /proc/self/exe,but it is returning the path of the calling
process and not the DLL which is called by calling process.
For eg: My process resides in /opt/myproc.exe. This myproc.exe calls DLL
which resides in /root/Desktop/myprocdl.dll . I need the path of my
DLL(which in this case if /root/Desktop/myprocdl.dll).
