Detecting path to shared object

Hi,

I'm running a process that already loaded mysharedobject.so. I'd like to know in a C program, where was this object loaded from.
In a shell script I would probably do something like
cat /proc/PID of the process/maps | grep mysharedobject.so

How does one do that?

Thanks,
fb0

lsof perhaps?

I'm interested in calling a C function, rather than running an application, and the purpose is to find out where a certain library is loaded from.
This is what "pldd" utility under Solaris does.

lsof is a utility, and isn't doing what I need.

/proc/ is the ultimate source of this information. So open /proc/PID/maps and parse it out.

Yes, but this is what I wanted to avoid. I still hope there is a more elegant solution.

There is not. All programs which obtain this information do so by reading /proc/.

The dynamic linker itself knows which file was loaded, but there is no interface provided for you to query that information.
