| unsigned integer type returned by the sizeof operator (typedef) | |
| signed integer type returned when subtracting two pointers (typedef) | |
| implementation-defined null pointer constant (macro constant) | |
| (C11) |
a type with alignment requirement as great as any other scalar type (typedef) |
| byte offset from the beginning of a struct type to specified member (function macro) | |
| Defined in header
