Basic types
Fundamental types defined by the language
Additional basic types and convenience macros
| Defined in header <stddef.h> | |
|---|---|
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 <stdalign.h> | |
| alignas (C11) | convenience macro, expands to keyword _Alignas (macro constant) |
| alignof (C11) | convenience macro, expands to keyword _Alignof (macro constant) |
| __alignas_is_defined (C11) | expands to integer constant 1 (macro constant) |
| __alignof_is_defined (C11) | expands to integer constant 1 (macro constant) |
| Defined in header <stdnoreturn.h> | |
| noreturn (C11) | convenience macro, expands to _Noreturn (macro constant) |
