This function is used to unlock the container present in the TW_CAPABILITY structure.
To access the container so that it may be modified, call L_TwainLockContainer. 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 the user must call L_TwainUnlockContainer to unlock the container. Note that this can also be accomplished using the C API GlobalLock and GlobalUnlock functions.
For an example, refer to L_TwainLockContainer.
