This example shows how to query character attributes.

#include <stdio.h>
#include <unidef.h>

int main(void) {

LocaleObject locale_object = NULL;

int          result = 0;
int          rc = ULS_SUCCESS;

         /*****************************************************************/
         /* Assumes LANG environment variable set to a valid locale name, */
         /* such as fr_FR                                                 */
         /*****************************************************************/

         rc = UniCreateLocaleObject(UNI_UCS_STRING_POINTER,
                                   (UniChar *)L"", &locale_object);

         if (rc != ULS_SUCCESS) {
           printf("UniCreateLocaleObject error: return code = %u\n", rc);
           return 1;
         }

         /* Query character attribute */

         result = UniQueryLower(locale_object, uni_char);

         if (result)
           printf("UniChar character %04X is a lowercase character\n", uni_char);

         else
           printf("UniChar character %04X is not a lowercase character\n", uni_char);


         return ULS_SUCCESS;
}
