According to one-definition rule, C++ constructs must be identically defined in every compilation unit they are used in.

As per ODR, two definitions contained in different source files are called to be identically defined if they token-for-token identical. The tokens should have same meaning in both source files.

Identically defined doesn’t mean character-by-character equivalence. Two definitions can have different whitespace or comments and yet be identical.

LTE: Charging-Rule-Base-Name and Charging-rule-Name in the CCA message

In the CCA message sent by the PCRF to PGW during the Initial Attach, may have "Charging-Rule-Base-Name" Or "Charging-rule-Name". I think "Charging-rule-Name" is sent as part of the Charging-Rule-Install , where the Rule is sent from the PCRF to PGW. "Charging-Rule-Base-Name" is sent as part of the preinstalled rules in the PGW.

Now the question is if the PCRF is getting integrated to thirdparty PGW. In this case how PCRF knows about the names installed in the PGW ?

thanks a lot for the responses and hints
