int
fromStringOrFallbackIfEnabled(
TYPE* result,
char const* string,
int stringLength);Load into the specified result the enumerator matching the specified string of the specified stringLength and return 0 if such an enumerator exists. Otherwise, if result supports a fallback enumerator, load into result the fallback enumerator value and return 0. Otherwise, return a non-zero value with no effect on result. The behavior is undefined unless TYPE is a bdlat enumeration type.
