This header was originally in the C standard library as <stddef.h>.
This header is part of the utility library.
Macros |
|
| implementation-defined null pointer constant (macro constant) |
|
| byte offset from the beginning of a standard-layout type to specified member (function macro) |
|
Types |
|
unsigned integer type returned by the sizeof operator (typedef) |
|
| signed integer type returned when subtracting two pointers (typedef) |
|
|
(C++11) | the type of the null pointer literal nullptr (typedef) |
|
(C++11) | trivial type with alignment requirement as great as any other scalar type (typedef) |
|
(C++17) | the byte type (enum) |
Functions |
|
|
(C++17) | convert std::byte to integer (function template) |
