for loop
This works:
import�std.stdio;
void�main()
{
int�x =�0;
int�y =�0;
for(;�((x��5)��(y��5));�x++,�y�++)
{
writeln(x + y = ,�x�+�y);
}
}
The question is easy: is it possible to insert x and y internally
in the for header? that is something like C#
for (int x = 0, int y = 0; .)
this doesn't work in D.
Re: for loop
for (int x = 0, int y = 0; .) for (int x=0, y=0; ...)

If you want to declare and initialize several variables in the for
loop, you can do it if they are of the same type:
for (int x = 0, y = 0; ...; .++x, ++y) { ... }

This is an ugly solution (and I'm not 100% sure it's valid D) but:
/+/
void main() {
{
short y = 0;
int x = 0;
for (; x 10; ++x, ++y)
{

eof of socketstream?
Hey guys, is there any way to find the end a socketstream? When I use: MemoryStream ms = new MemoryStream(); while (s.socket().isAlive()) ms.write(s.getc()); I run into an endless loop. The socket doesn't send the size of the data, so I need to know when I received all the data. How can I figure out that I received all data? thx for any help!
Re: MySQL
The way I did it is 1) Download C connector from mysql's website, 6.0.2 is version headers were made for. Remember you'll need the 32-bit one if you're using DMD on Windows. 2) Create the binding functions using extern(System). 3) For Windows, use 'coffimplib libmysql.dll libmysql.lib', and build with PathToFile/libmysql.lib. Example: 'dmd test.d libmysql.lib' 3b) For Linux, just link to libmysqlclient. a with -Llibmysqlclient.a or by just passing path. 4) Make sure that libmysql.dll (for Windows) is in the application folder otherwise you'll get errors when trying to run.

no-argument constructor: is this a bug?
struct A(uint samples){
float[samples] _data = void;
this(float val = 0.0f){ fill(_data[], val); }
}
auto a = A!8();
a._data is filled with garbage instead of zeros because the
no-argument constructor is called instead of the one that I've
defined.

structs are always default-constructible, and, as a tie-breaker, a
function definition that has the exact number of arguments is considered
a better match one that has to supply default-arguments to match. You
could use a static opCall to make auto a = A!8() work.

It should be illegal to have a struct constructor where all of its parameters
have default arguments. If you want to have all default arguments, then use
static opCall instead.

You should add 'extern(Windows)', but it would not work anyway.
Can someone confirm the oplink does not handle this type of module
(undecorated stdcall functions)?
You can try
// - libmysql.def ---
LIBRARY libmysql.dll
EXETYPE NT
SUBSYSTEM WINDOWS
EXPORTS
_mysql_init@4=mysql_init
//
// --- mysqltest.d
import libmysql;
alias void MYSQL;
int main()
{
MYSQL *m = libmysql.mysql_init(null);
return 0;
}
// ---
// --- libmysql.di ---
alias void MYSQL;
export extern (Windows) MYSQL *mysql_init(MYSQL *);
//
$ implib /system libmysql.lib libmysql.def
$ dmd mysqltest.d libmysql.lib
It works..
