How to find the memory usage of shared library running in Linux?
 

I need to find the memory usage of a shared library loaded in Linux environment.

I need this information for deciding on whether to make the library part in to application or a seperate application itself.

Take a look at /proc/<pid>/smaps. It reports the memory usage for each shared object loaded in memory. Please, see man proc for details.

/proc/pid/smaps and pmap command are not giving the complete size occupied by a shared library. The size depends on the methods from shared lib that are currently attached to the process.

Hmmm... maybe it's necessary some more sophisticated tool like memprof, valgrind or exmap. I have no experience with these tools, anyway.
