Using DBcursor- c_count

Question

I am trying to use the DBcursor->c_count method to count the number of duplicate records but I not sure how to set it up.
DB *dbp;
DBC *dbcp;
DBT key;
DBT data;
long recno = 1;
long dup_records = 0;
db_recno_t *count = 0;
// Database is opened with duplicate support
dbp->cursor(dbp,NULL,&dbcp,0);
memset(&key,0,sizeof(DBT));
memset(&data,0,sizeof(DBT));
key.data = &recno;
key.size = sizeof(long);
dbcp->c_get(dbcp,&key,&data,DB_SET);
dbcp->c_count(dbcp,count,0);
This does not work.

Answer 1

ret = cursor->c_count(c,&count,NO_FLAGS);
I could not get this to work.
On Windows DB->cursor will not accept a reference to the count variable also the NO_FLAGS variable is undeclared.
long Count(DBC *dbcp, long recno)
     DBT key;
     DBT data;
     int ret;
     db_recno_t *count = 0;
     long total;
     count = (db_recno_t*)malloc(sizeof(db_recno_t));
     memset(&key,0,sizeof(DBT));
     memset(&data,0,sizeof(DBT));
     key.data = &recno;
     key.size = sizeof(long);
     ret = dbcp->c_get(dbcp,&key,&data,DB_SET);
     if(ret != 0)
          free(count);
          if(ret == DB_NOTFOUND)
               return(0);
          else
               printf("Count() could not get record: %s",db_strerror(ret));
exit(0);
     ret = dbcp->c_count(dbcp,count,0);
     if(ret != 0)
          free(count);
          print("Count() could not read count: %s",db_strerror(ret));
exit(0);
     total = *count;
     free(count);
     return(total);
}
