Yes and you shouldn't lie. :)

That's a good idea, which you can do yourself but I don't think you can

@trusted is exactly for that. It can

@trusted is exactly for that. It can be called from @safe code:
@trusted @nogc ubyte[n]

What about this:

What about this
Or simpler,
while (left)
left -= fread(buf[n-left .. $].ptr,
- Fixed-length arrays are value types. You may not want to return them
if n is very large.
- Every array has the .ptr property that gives the pointer to the first
element.
- What can be helpful to you here is the fact that you can treat any
memory as a slice:
import core.stdc.stdlib;

Hi all,
I am writing a program to read device /dev/urandom file to get
some random bytes. I am trying to bypass D's GC as I know the
length of the buffer needed. I tried using std.stdio.File and
rawRead but File cannot be used with @nogc. So I used
core.stdc.stdio and used traditional C
