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".
