Hi All, I cannot seem to understand whats wrong with this:
// main.d
import std.stdio;
import std.digest.md;
import std.file;
string md5sum(const string fname)
{
MD5 hash;
File f = File(fname, "rb");
foreach( ubyte[] buf; f.byChunk(4096))
{
hash.put(buf);
}
string s = toHexString!(LetterCase.lower)(hash.finish());
writeln(s); //This is correct
return s;
}
void main()
{
string crc = md5sum("main.d");
writeln(crc); //This is garbage
}
The writeln in md5sum prints correctly, but the "return s" seems
to mess it up? What's going on?
Thanks for you time,
-Andy
