Name

The iswpunct() function tests whether ’wch’ can be classfied wide punctuation character i.e. it belongs to class punct(see defns for definition)

The characters that can be classified as alphabets, digits, space or control characters donot belong to punctuation wide-character code.

The result of this function is undefined unless the argument is WEOF or a valid wchar_t value.

The functionality of this API is independent of the program’s current locale and so it returns non-zero for all the characters (of various locales supported) that belong to the class punct, irrespective of the locale they belong to.

#include<wctype.h> //iswpunct()
#include<stdio.h>  //printf()
int test_iswpunct()
{
 
   int arr[]={0x3003,’3’,0x301C,’*’, ’+’};
   int i = 0;
   int size = 5;
   for( i=0; i<size; i++)
   {
     int ret = iswpunct(arr[i]);//call to the API with chars in arr[]
     if( (!ret) != 0 )
     {
         printf("\n0x%x is not wide punc char ", arr[i]);
     }
     else
     {
         printf("\n0x%x is a wide punc char", arr[i]);
     }
   }
printf("\n");
}

Output

0x3003 is a wide punc char
0 0x33 is not  wide punc char
0x301c is a wide punc char
0x2a is a wide punc char
0x2b is a wide punc char
