CHAPTER 10 LIBRARY FUNCTIONS
(1) ctype.h
This header is used to define character and string functions. In this standard header, the following library
functions have been defined.
However, when the compiler option -ZA (the option that disables the functions not compliant with ANSI
specifications and enables a part of the functions of ANSI specifications) is specified, _toupper and _tolower
are not defined. Instead, tolow and toup are defined. When -ZA is not specified, tolow and toup are not
defined. The function to be declared differs depending on the options and the specification models.
