CubeSuite+ V2.00.00 CHAPTER 6 FUNCTIONAL SPECIFICATIONS iscntrl Identification of control character [Classification] Standard library [Syntax] #include <ctype.h> int iscntrl(int c); [Return value] These macros return a value other than 0 if the value of argument c matches the respective description (i.e., if the result is true). If the result is false, 0 is returned. [Description] This function is a macro that checks whether a given character is a control character (0x00 to 0x1F or 0x7F). This macro is defined only when c is made true by isascii or when c is EOF. A compiled subroutine can be used instead of the macro definition, which is invalidated by using "#undef iscntrl".
