-/** @file
- Single-byte character classification, case conversion macros, and
- function declarations.
-
- The header <ctype.h> declares several functions useful for testing and mapping
- characters. In all cases, the argument is an int, the value of which shall be
- representable as an unsigned char or shall equal the value of the macro EOF.
- If the argument has any other value, the behavior is undefined.
-
- The behavior of these functions is affected by the current locale. The
- default is the "C" locale.
-
- The term "printing character" refers to a member of a locale-specific
- set of characters, each of which occupies at least one printing position on an output
- device; the term control character refers to a member of a locale-specific
- set of characters that are not printing characters.
