/*
I dont know if this is a bug... but its a strange behavior...
readf documentation:
abstract int readf(...);
Scan a string from the input using a similar form to C's scanf and std.format. 
*/

/*
Content of file that is opened:
1-2-3-4
*/

/*C sample*/
#include <stdio.h>


int main(int argc, char *argv[])
{
  FILE *fp = fopen(argv[1],"r");
  int num[4];
  int res = fscanf(fp,"%d-%d-%d-%d",&num[0],&num[1],&num[2],&num[3]);
  printf("\n%d-%d-%d-%d  %d",num[0],num[1],num[2],num[3],res);
  fclose(fp);
  return 0;
}
/* Output */
1-2-3-4  4

/*D sample (dmd 1.034 linux)*/

import std.stdio;
import std.stream;

int main(string[] args)
{
        File f = new File(args[1], FileMode.In);
        int num[4];
        TypeInfo[] types = [typeid(int)];
        int res = f.readf("%d-%d-%d-%d",&num[0],&num[1],&num[2],&num[3]);
        printf("\n%d-%d-%d-%d  %d",num[0],num[1],num[2],num[3],res);
        f.close();
        return 1;
}

/* Output */
1-2-3-0  3

/* if i put a empty space at end of file content all works fine.*/
