No, wait, the first code is even better because it uses the

the MAX_COMPUTERNAME_LENGTH define, too, nice!
Using this will return only the first 15 characters of the
computer name, if longer.
Please use the unicode version of the function GetComputerNameW
instead of the ANSI one (GetComputerNameA), because the second
one has a known bug, returning always 0 as required buffer size.
import std.stdio;
import std.c.windows.windows;
wstring getComputerName()
{
enum ERROR_BUFFER_OVERFLOW = 111;
uint size;
if (GetComputerNameW(null, &size) == 0 && GetLastError() ==
ERROR_BUFFER_OVERFLOW)
{
wchar[] buf = new wchar[size];
if (GetComputerNameW(buf.ptr, &size))
return buf[0 .. size].idup;
}
return "Unknown";
}
int main(string[] argv)
{
writeln(getComputerName());
getchar();
return 0;
}
I changed the code to use GetComputerName, so I guess
GetComputerNameA is actually used, right? Anyway it's not really
important, I'm just playing around with winAPIs to get a feel of
things. I'm making a simple health cheat for a game I've written
in FreeBasic!
I'm going through a nice D2 tutorial here:

If anyone reading this can save me some time and help me with
this: How to declare a byte pattern, for example to pass to
WriteProcessMemory?
I guess it's uint[] bytes;
How do I set it to 0x12345678 ?
