### Using long long Integers

The C compiler allows the type specifier long long. The longlong pragma controls this behavior and has no corresponding item .

If this setting is off, using long long causes a syntax error.

In an enumerated type, you can use an enumerator large enough for a long long. For more information, see Enumerated Types.

However, long long bitfields are not supported.

You control the long long type with #pragma longlong. To check this setting, use __option (longlong). By default, this pragma is on.
