pub type c_long = i64;
Expand description

Equivalent to C’s signed long (long) type.

This type will always be i32 or i64. Most notably, many Linux-based systems assume an i64, but Windows assumes i32. The C standard technically only requires that this type be a signed integer that is at least 32 bits and at least the size of an int, although in practice, no system would have a long that is neither an i32 nor i64.
