The <iso646.h> header is part of the standard library of the C programming language which provides a set of object-like macros as an alternative spelling for C operators that contain &, |, ~, !, and ^. This header was added in Normative Addendum 1 in order to provide support for international character sets that might not have these symbols. This header provides eleven such macros.
Macros[edit]
The header provides the following macro definitions:
| Macro Name | Description | Since |
|---|---|---|
| and | Expands to && | NA1 |
| and_eq | Expands to &= | NA1 |
| bitand | Expands to & | NA1 |
| bitor | Expands to | | NA1 |
| compl | Expands to ~ | NA1 |
| not | Expands to ! | NA1 |
| not_eq | Expands to != | NA1 |
| or | Expands to || | NA1 |
| or_eq | Expands to |= | NA1 |
| xor | Expands to ^ | NA1 |
| xor_eq | Expands to ^= | NA1 |
