Object Data Manager Library (libodm.a)
The odm_lock subroutine is used by an application to prevent other applications or methods from accessing an object class or group of object classes. A lock on a directory path name does not prevent another application from acquiring a lock on a subdirectory or object class within that directory.
The odm_lock subroutine returns a lock identifier that is used to call the odm_unlock subroutine.

Failure of the odm_lock subroutine sets the odmerrno variable to one of the following error codes:
