:mrdocs:

Decode an enumeration from an integer, using a fallback if needed.

== Synopsis

Declared in `<bdlat_enumutil.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
template<class TYPE>
static
int
fromIntOrFallbackIfEnabled(
    TYPE* result,
    int number);
----

== Description

Load into the specified `result` the enumerator matching the specified `number` 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.

== Return Value

0 on success, and a non‐zero value otherwise
