‑‑enum_is_int

2.1.42. ‑‑enum_is_int

This option forces the size of all enumeration types to be at least four bytes.

This option is switched off by default and the smallest data type is used that can hold the values of all enumerators.

Note

The ‑‑enum_is_int option is not recommended for general use.
