*
* Abstract:
* This is the interface file for the Network Address List class. This
* class manages the data associated with a network address. Network
* addresses can be one of three types: aggregated channel, transport
* connection, or non-standard. A variety of structures, objects, and
* Rogue Wave containers are used to buffer the network address data
* internally.
*
* Caveats:
* A network address may contain an Object Key if it is a non-standard
* type. When created locally with "API" data, checks are made to ensure
* that the constraints imposed upon Object Keys are not violated. Checks
* are also performed to validate certain types of strings which may exist
* in a network address. If however, a network address is created from
* "PDU" data received from a remote site no such validation is performed.
* We are taking no responsibility for validation of data originated by
* other GCC providers.

/*
* UINT LockNetworkAddressList ();
*
* Public member function of CNetAddrListContainer.
*
* Function Description:
* This routine is used to "lock" the "API" data for this object. This
* results in the lock count for this object being incremented. When the
* lock count transitions from 0 to 1, a calculation is made to determine
* how much memory will be needed to hold any "API" data which will
* be referenced by, but not held in, the list of GCCNetworkAddress
* structures which is filled in on a call to GetNetworkAddressListAPI.
* This is the value returned by this routine in order to allow the calling
* object to allocate that amount of memory in preparation for the call to
* GetNetworkAddressListAPI.
*
* Formal Parameters:
* None.
*
* Return Value:
* The amount of memory, if any, which will be needed to hold "API" data
* which is referenced by, but not held in, the list of GCCNetworkAddress
* structures provided as an output parameter to the
* GetNetworkAddressListAPI call.
*
* Side Effects:
* The internal lock count is incremented.
*
* Caveats:
* The internal lock count is used in conjuction with an internal "free"
* flag as a mechanism for ensuring that this object remains in existance
* until all interested parties are through with it. The object remains
* valid (unless explicity deleted) until the lock count is zero and the
* "free" flag is set through a call to FreeNetworkAddressList. This allows
* other objects to lock this object and be sure that it remains valid
* until they call UnLock which will decrement the internal lock count. A
* typical usage scenerio for this object would be: A CNetAddrListContainer
* object is constructed and then passed off to any interested parties
* through a function call. On return from the function call, the
* FreeNetworkAddressList call is made which will set the internal "free"
* flag. If no other parties have locked the object with a Lock call,
* then the CNetAddrListContainer object will automatically delete itself when
* the FreeNetworkAddressList call is made. If, however, any number of
* other parties has locked the object, it will remain in existence until
* each of them has unlocked the object through a call to UnLock.

* Function Description:
* This routine is used to "unlock" the "API" data for this object. This

* lock count transitions from 1 to 0, a check is made to determine
* whether the object has been freed through a call to

*
* Formal Parameters:
* None.
*
* Return Value:
* None.
*
* Side Effects:
* The internal lock count is decremented.
*
* Caveats:
* It is the responsibility of any party which locks a CNetAddrListContainer
* object by calling Lock to also unlock the object with a call to UnLock.
* If the party calling UnLock did not construct the CNetAddrListContainer
* object, it should assume the object to be invalid thereafter.
