The ifx_gl_ismxdigit() function

Syntax

#include <ifxgls.h>
...
int ifx_gl_ismxdigit(mb, mb_byte_limit)
      gl_mchar_t *mb;
      int mb_byte_limit;

mb

A pointer to the multibyte character whose character classification you want to determine.

mb_byte_limit

The integer number of bytes to read from mb to try to form a complete multibyte character. If mb_byte_limit is IFX_GL_NO_LIMIT, the ifx_gl_ismxdigit() function reads as many bytes as necessary from mb to form a complete character.

Usage

Any multibyte versions or alternative representations of these hexadecimal digits that the locale might define (for example, Hindi or Kanji digits) are not in this class. Instead, they are in the alpha class.

Characters in this class are also in the graph and print classes. No characters in the blank, space, punct, or cntrl classes are in this class.

To determine whether a multibyte character contains a decimal digit, you can use the ifx_gl_ismdigit() function. Use the ifx_gl_ismalnum() function to test whether a multibyte character contains an alphabetic character or a digit.

Locale information

The LC_CTYPE category of the current locale affects the behavior of this function because it defines the xdigit character class.

Return values

>0

The mb character is in the xdigit character class.

0

The function was not successful, and the error number is set to indicate the cause. See the Errors section.
