Usage

The JagUnlockCollection method releases a lock on a collection. A locked collection is automatically released when the object’s method execution is completed. However, to make your application more efficient and prevent deadlocks, unlock a collection when you are finished updating or reading the shared variable in the collection so that other objects can access the collection right away.

See Appendix C, “Creating C Components,” in the EAServer Programmer’s Guide for more information.
