Re: ioctl to set mixer volume

A d-lang program which sets my volume to zero.

void main() {

The function .fileno returns the "underlying handle" of the

Here you could avoid C stdio and just use posix functions like
`core.sys.posix.fcntl
: open` that returns a file descriptor directly.

Not quite straightforward, but "void function()" is actually a

It seems the detection of first assignment only happens when the field and constructor have the same parent, so it doesn't work either if the field is from a base or derived class (your case by means of casting 'this'). I don't think this is intended rather it appears to be a bug/deficiency in the constructor flow analysis of DMD, which from what I'm reading is very rudimentary.

From language spec [1]: "the name of the static foreach variable

variable declaration (for constants) or an alias declaration (for
symbols).
Enums are treated differently, so your 'sym' is not an alias to
the original enum but an enum itself with the same value. Because
of that, fullyQualifiedName or any template with alias argument
will just get the sym temporary not the enum from the symbols
tuple.
This code should work:
static foreach(i, _; symbols!a){
pragma(msg, fullyQualifiedName!(symbols!a[i]));
// or manually aliased, but you need to use regular
foreach or {{ }} to avoid redefinitions.
alias sym = symbols!a[i];

The way map is designed is to call its predicate on each front
call and filter calls it twice with the number 2.
https://github.com/dlang/phobos/blob/master/std/algorithm/iteration.d#L604
You can use "cache" to avoid the double front call on any range.
z.map!(a => tuple!("number","iseven")(a, a.isEven))
.cache
.filter!(a => a.iseven)

https://stackoverflow.com/questions/57153617/random-segmentation-fault-in-d-lang-on-switch-break
Hope someone can help!
Could be the statement in the actual switch(), which is
accessing a pointer "codecpar".
switch (stream.codecpar.codec_type)
^
This could be null and you aren't checking for it. I find that
D sometimes doesn't have the correct line numbers for debug
info, even when not doing an optimized build. So it could
really be anything in that function.
The root cause could be a lot of things though, some bad
codegen or otherwise. Could add a check to make sure though.
I ran the program after adding
enforce (stream.codecpar != null);
and nothing changed, and by nothing I mean that DMD in debug
mode still doesnt crash but DMD in release does (like 70% of
the time), I think its more important to address that issue
because I can't seem to find any explenation of this behaviour,
yet it occurs.
The struct AVStream is different on the D side (avformat.d) than
the original C header, at least on my PC using ffmpeg 4.1.4.
So instead of getting codecpar member we get some unrelated data
and dereferencing it can crash the program.
I tried using the DPP project, it errors out but the generated
file is almost there, just commenting 1 line and changing some
not found type pointer member to void pointer I got a working
example with your same code.
Here is the updated struct part, the program will run fine with
this layout.
struct AVStream
{
int index;
int id;
AVCodecContext* codec;
void* priv_data;
AVRational time_base;
c_long start_time;
c_long duration;

I'll give you another option if you just need that fix. Patch your phobos64.lib in the original dmd install directory using cygwin and sed, just run this exact command on cygwin prompt, editing the path to your case: sed -bi 's/%zu): /%llu):/' /c/d/dmd2/windows/lib64/phobos64.lib you can patch the 32bit libs if you need them. Then just run dub without "--compiler=" option to use your original dmd.

Registers are: rcx = 0x0010, r10 = 0x it seems like ( str[i] == '\0') So the program try to print from an invalid pointer and the StackTrace/Throwable object is somewhat related.

I think you can't do a partial statement in a mixin.
But this works by declaring pointers to functions and assigning a
function literal to them.
import std.stdio;
void main()
{
auto dg = (uint i){ writeln('a' , " - ", i); };
enum letters = ['A', 'B', 'C'];
static foreach(ch; letters)
{
mixin("void function(uint i) print" ~ ch ~ ";");
dg = (uint i){ writeln(ch , " - ", i); };
mixin("print" ~ ch ~ " = dg;");
}
printA(1);
printB(2);
printC(3);
}

Am I doing something wrong or is there some issue with curl or

there is some other library that can help. If I get this
working, it could potentially save myself and many others hours
per week.
There is a limit of 50 concurrent messages per thread [1] in
byLineAsync also the transmitBuffers argument takes part in.
So using multiple byLineAsync at same time/thread is going to
block the process, I'm not sure if this is a bug or is by design.
You could use download() in a parallel foreach, something like
this:
import std.stdio;
import std.parallelism;
import std.net.curl;
import std.typecons;
void main()
{
auto connections = 3; // 3 parallel downloads
defaultPoolThreads(connections - 1);
auto retries = 4; // try up to 4 times if it fails
auto logList = [
tuple("dlang.org", "log1.txt"),
tuple("dlang.org", "log2.txt"),
tuple("dlang.org", "log3.txt"),
tuple("dlang.org", "log4.txt"),
tuple("dlang.org", "log5.txt"),
tuple("dlang.org", "log6.txt")];
foreach (log; parallel(logList, 1))
{
HTTP conn = HTTP();
foreach (i; 0 .. retries)
{
try
{
writeln("Downloading ", log[0]);
download(log[0], log[1], conn);
if(conn.statusLine.code == 200)
{
writeln("File ", log[1], " created.");
break;
}
}
catch (CurlException e)
{
writeln("Retrying ", log[0]);
}
}
}
}
