Dear Rooters,
The stdin redirection doesn't seem to work OK for macros using cin,
while scanf() seems to work OK. Is it a feature or a bug? It would be
nice if the stdin could be redirected for macros using cin, too.
An example:
root [0] .x m1.C < d1.dat # The first execution is OK
1
2
root [1] .x m1.C < d1.dat # Subsequent executions fail (no output)
root [2] cin.good()
(int)0
root [3] .x m2.C < d1.dat # m2.C uses scanf()
1
2
root [4] .x m2.C < d1.dat # Subsequent executions are OK
1
2
$ cat m1.C
{
#include <iostream.h>
Int_t n;
while (cin >> n)
cout << n << endl;
}
$ cat m2.C
{
#include <stdio.h>
Int_t n;
while (scanf("%d", &n) == 1)
printf("%d\n", n);
}
$ cat d1.dat
1
