# Type Definition std::os::raw::c_ulonglong 1.1.0[−][src]

    type c_ulonglong = u64;

Equivalent to C's `unsigned long long` type.

This type will almost always be `u64`, but may differ on some systems. The C standard technically only requires that this type be an unsigned integer with the size of a `long long`, although in practice, no system would have a `long long` that is not a `u64`, as most systems do not have a standardised `u128` type.
