Universally-unique identifiers (UUIDs) are often used in the identities of Ice objects. The C++ standard does not include a function for generating UUIDs, therefore Ice provides the IceUtil::generateUUID function for use in portable applications. The signature of generateUUID is:
C++
std::string generateUUID();
The function returns a string like the following:
02b066f5-c762-431c-8dd3-9b1941355e41
Each invocation returns a new identifier that differs from all previous ones.
