 void split(char **arr, char *str, const char *del) {
   char *s = strtok(str, del);
 
   while(s != NULL) {
     *arr++ = s;
     s = strtok(NULL, del);
   }
 }

 int main() {
   char *str = "10,20,30";
   char *arr[3];
   const char *del = ",";
   int i = 0;
   split(arr, str, del);

   while(i<3)
     printf("%s\n", *(arr+i++));
 }

in c++, must transfer string to char*!

 int main() {
        char *arr[3];
        char *s = (char*)"_";
        char buff[80];
        strcpy (buff, "DR_1_Disable.xml");
        split(arr, buff, s);

   while(i<3)
     printf("%s\n", *(arr+i++));
 }
