* Abstract:
* This is the interface file for the class CInvokeSpecifierListContainer.
* This class manages the data associated with an Application Invoke
* Request or Indication. This includes a list of applications to be
* invoked. The CInvokeSpecifierListContainer data container utilizes a
* CSessKeyContainer container to buffer part of the data associated with each
* application invoke specifier. Each application invoke specifier also
* includes a capability ID whose data is buffered internally by the
* using a CCapIDContainer container. The list of application
* invoke specifiers is maintained internally by the class through the use
* of a Rogue Wave list container.
*
* Caveats:
* None.

* UINT LockApplicationInvokeSpecifierList ();
*
* Public member function of CInvokeSpecifierListContainer.
*
* 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 GCCAppProtocolEntity
* structures which is filled in on a call to GetApplicationInvoke-
* SpecifierList. 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 GetApplicationInvokeSpecifierList.
*
* Formal Parameters:
* None.
*
* Return Value:
* The amount of memory which will be needed to hold "API" data
* which is a list of GCCAppProtocolEntity structures.
*
* 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 FreeApplicationInvokeSpecifierList.
* 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: An
* CInvokeSpecifierListContainer object is constructed and then passed off
* to any interested parties through a function call. On return from the
* function call, the FreeApplicationInvokeSpecifierList call is made which
* will set the internal "free" flag. If no other parties have locked the
* object with a Lock call, then the CInvokeSpecifierListContainer object
* will automatically delete itself when the FreeApplicationInvoke-
* SpecifierList 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.
