[Linux-cluster] creating file locks on a gfs volume

Not sure if this is the correct place for discussing this, but here it is.
On a gfs cluster running dlm locking, is it possible to create a file
lock on a file on the volume? (e.g. in C).
Have seen that there is a libdlm library, and have not tested yet. By
calling dlm_lock, would gfs be aware of the file lock?

This is to allow an application we are developing to create file locks
with different lock modes, based on what the app is doing (e.g. CR /
CW / PW / EX locks).
