The code is as follows, I assume this code would work in older version of D compiler, but in current version of D compiler, it halts. Is there anything changed in the scanf function of MemoryStream, and how should I fix to code?

Thanks ^_^



private import std.stream;

void main()
{
MemoryStream ms = new MemoryStream("1.23 4.56 7.89 9.01 ");
float a, b, c, d;
ms.scanf("%f %f %f %f", &a, &b, &c, &d);
}

Before the scanf, I think you need
ms.position = 0;

hahaha... not laughing at you, but it's a funny side affect:

There is no scanf in Stream or MemoryStream, but it is accessible because std.c.stdio is imported inside Stream, making the stdin scanf available. stdin scanf is waiting for you to type.

Use ms.readf, then.
