pub type c_ulong = u64;Expand description
Equivalent to C’s unsigned long type.
This type will always be u32 or u64. Most notably, many Linux-based systems assume an u64, but Windows assumes u32. The C standard technically only requires that this type be an unsigned integer with the size of a long, although in practice, no system would have a ulong that is neither a u32 nor u64.

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
