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?
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
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.Originally Posted by Salem
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.
Code://try //{ if (a) do { f( b); } while(1); else do { f(!b); } while(1); //}
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.
Code://try //{ if (a) do { f( b); } while(1); else do { f(!b); } while(1); //}
