Detailed Description

Functions to convert different CPE notations into each other.

This library provides functions to read the CPE 2.2 URI binding of a CPE or the CPE 2.3 formatted string binding of a CPE into a CPE struct that corresponds to the WFN naming of a CPE. Further functions to convert the CPE struct into the different bindings are provided. This file also contains a function that checks if one CPE (represented in a CPE struct) is a match for an other CPE (also represented in a CPE struct).
