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