NAME
     isxdigit -- hexadecimal-digit character test

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <ctype.h>

     int
     isxdigit(int c);

DESCRIPTION
     The isxdigit() function tests for any hexadecimal-digit character.  For
     single C chars locales the value of the argument is representable as an
     unsigned char or the value of EOF.  In the ASCII character set, this
     includes the following characters (with their numeric values shown in
     octal):

     060 ``0''	   061 ``1''	 062 ``2''     063 ``3''     064 ``4''
     065 ``5''	   066 ``6''	 067 ``7''     070 ``8''     071 ``9''
     101 ``A''	   102 ``B''	 103 ``C''     104 ``D''     105 ``E''
     106 ``F''	   141 ``a''	 142 ``b''     143 ``c''     144 ``d''
     145 ``e''	   146 ``f''

RETURN VALUES
     The isxdigit() function returns zero if the character tests false and
     returns non-zero if the character tests true.

SEE ALSO
     ctype(3), ascii(7)

STANDARDS
     The isxdigit() function conforms to ISO/IEC 9899:1990 (``ISO C90'').
