Comments

This function is used to unlock the container present in the TW_CAPABILITY stucture.

To access the container so that it may be modified, call LTwain::LockContainer. This function provides the user with a pointer to the container. At this point the container may be changed. When the user has finished changing the container he or she must call LTwain::UnlockContainer to unlock the container. Note that this can also be accomplished using the C DLL GlobalLock and GlobalUnlock functions.
