For example, I'm trying to compare a wchar buffer with a wstring using
slices:
x[0..$] == y[0..$]
It fails. I think because x has length 1024. If do
x[0..y.length] == str[0..y.length]
it fails, also because y has length 1024(since it was generated from a
buffer and the length wasn't set correctly).
So you fill the buffer with a call to some Windows function. The Windows
function either returns the amount of data it wrote, and/or it
zero-terminates the string which it writes.
If it returns the length, you use that when slicing the buffer. Then you
can compare.
If it zero-terminates, you search for zero in the buffer and count along
to determine the length. I wanted to say that there's a function for
this in phobos, but fromStringz [1] seems to be for char arrays only.
