Is there way to write the myStruct data to the file in a single

Thanks for any assistance.

f.rawRead( header );

~15k samples x 2 sin() waves/composite wave x 16 DTMF tones = 16

I love D.
What's with the 4 bytes of zero?
I miss-counted. All is well!
Thanks Ali / Steven
Hmm...well this is what I did and sort of got what I wanted; it
did compile and write data!
auto myStruct = new mystruct[1];
File f = File("myFile.wav", "wb");
f.rawWrite(myStruct); //this is 44 bytes
f.rawWrite(shortWaveArray);
What I got in the file was this:
-my 44 byte myStruct data + (4

Dear D-ers,
I enjoyed reading some details of incorporating AVX into math code
from Johan Engelen's programming blog post:
http://johanengelen.github.io/ldc/2016/10/11/Math-performance-LDC.html
Basically, one can use the ldc compiler to insert avx code, nice!

Some are available on my website
http://druntime.dpldocs.info/core.sys.html
but the source doesn't include much so it is a bit sparse and all
the version overloads can be awkward to read.
I can't find the core.sys documentation in the library reference.
I thought that functionality was removed but clearly the source
files exist in druntime:

Same goes for std.windows:

Allocating a dynamic array there is egregious pessimization. The
following works the same but this time the static array of a single S
will be
rawRead and rawWrite work with slices (arrays) of things. You need to
use an array of your struct even if there is a single item. Here is an
example:
import std.stdio;
import std.file;
struct S {
int i;
double d;
}
void readFrom(string name) {

I feel I didn't make it clear enough that extracting the code

not even sure it runs on Linux. So I really wouldn't suggest
going down that route.

I have some work done in this regard, but sadly the library
itself isn't really usable at all so if you want to put in the
effort you'd have to probably extract

Hi there,
I'm new in dlang I specially like betterC. I was hoping that d

are not. Is there another way how to use async/await in dlang

Thank you for your help
