| Return the non‐modifiable string representation corresponding to the specified enumeration `value`, if it exists, and a unique (error) string otherwise. The string representation of `value` matches its corresponding enumerator name with the "e_" prefix elided. For example: ` bsl::cout << SystemClockType::toAscii(SystemClockType::e_REALTIME); ` will print the following on standard output: ` REALTIME ` Note that specifying a `value` that does not match any of the enumerators will result in a string representation that is distinct from any of those corresponding to the enumerators, but is otherwise unspecified.
