Synopsis

Return values

Detailed description

The iswlower() function tests whether ’wch’ is a wide-character which is from among lower-case alphabets.

Characters that belong to class cntrl, class punct and digit are not a part of class lower(see defns for definition).

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 lower(see defns for definition), irrespective of the locale they belong to.

Examples

#include<wctype.h> //iswlower()
#include<stdio.h> //printf()
int test_iswlower()
{
   int arr[]={ 0x0126, 0xee, ’r’ , ’9’ , ’g’, 0xFF51, 0x0451, 0x03CE };
   int i = 0;
   int size = 8;
   for( i=0; i<size; i++)
   {
     int ret = iswlower(arr[i]); //call to the API with chars in arr[]
     if( (!ret) != 0 )
     {
        printf("\n%lc is not wide lower-case ", arr[i]);
     }
     else
     {
        printf("\n%lc is wide lower-case", arr[i]);
     }
   }
printf("\n");
}
