   2 @chapter Character Type Macros and Functions (@file{ctype.h})
   3 This chapter groups macros (which are also available as subroutines)
   4 to classify characters into several categories (alphabetic,
   5 numeric, control characters, whitespace, and so on), or to perform
   6 simple character mappings.
   7
   8 The header file @file{ctype.h} defines the macros.
