pub type c_ulong = c_ulong;

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.
