Header File (ctype.h)
The ctype.h header file provides interfaces for developing multi-threaded applications.
It contains the prototype declarations of the functions that classify character-coded
integer values according to the rules of the coded character set identified by the last
successful call to setlocale(). These functions are supplied both as library functions
and as macros defined in the ctype.h header file.
Summary of Change
Some compiler defined symbols are obsoleted and have been removed from the ctype.h
header file in HP-UX 11i v1.6 to eliminate a potential source of name pollution.
Details of Change
The following obsolete symbols are removed from the ctype.h header file:
# define _U 01
# define _L 02
# define _N 04
# define _S 010
# define _P 020
# define _C 040
# define _B 0100
