/* FUNCTION <<isspace>>---whitespace character predicate INDEX isspace ANSI_SYNOPSIS #include <ctype.h> int isspace(int <[c]>); TRAD_SYNOPSIS #include <ctype.h> int isspace(<[c]>); DESCRIPTION <<isspace>> is a macro which classifies ASCII integer values by table lookup. It is a predicate returning non-zero for whitespace characters, and 0 for other characters. It is defined only when <<isascii>>(<[c]>) is true or <[c]> is EOF. You can use a compiled subroutine instead of the macro definition by undefining the macro using `<<#undef isspace>>'. RETURNS <<isspace>> returns non-zero if <[c]> is a space, tab, carriage return, new line, vertical tab, or formfeed (<<0x09>>--<<0x0D>>, <<0x20>>). PORTABILITY <<isspace>> is ANSI C. No supporting OS subroutines are required. */ #include <_ansi.h> #include <ctype.h> #undef isspace int _DEFUN(isspace,(c),int c) { return(__ctype_ptr__[c+1] & _S); }
