How array concatenation works... internally
Hi,
I'd like to understand how array concatenation works internally,
like the example below:
//DMD64 D Compiler 2.072.2
import std.stdio;
void main(){
string[] arr;
arr.length = 2;
arr[0] = "Hello";
arr[1] = "World";
writeln(arr.length);
arr = arr[0..1] ~ "New String" ~ arr[1..2];
writeln(arr.length);
foreach(string a; arr){
writeln(a);
}
}
http://rextester.com/DDW84343
The code above prints:
2
3
Hello
New String
World
So, It changes the "arr" length and put the "New String" between
the other two. It's very fast with some other tests that I made.
Now I'm curious to know what's happening under the hood. It's
related to memcpy?
On Phobos "array.d" source I've found this:
/// Concatenation with rebinding.
void opCatAssign(R)(R another)
{
auto newThis = this ~ another;
move(newThis, this);
}
But now I'm having problem to find how I can reach this "move"
function, since I couldn't find any "move" on the "std" folder.
Thanks in advance.

Trouble with DLL address
I have a DLL which exports a function GetFunction. GetFunction

Here is the code.
dll64.c -
#define WIN32_LEAN_AND_MEAN
#include windows.h
int __stdcall RealFunction(int a)
{
return a + 1;
}
typedef int (__stdcall *FuncPtr)(int);
FuncPtr __stdcall GetFunction()
{
return RealFunction;
}
mydll64.def
LIBRARY mydll64.dll

GetFunction
-
build with MSVC64:
cl -c dll64.c -Fomydll64.obj
link /DLL /OUT:mydll64.dll mydll64.obj /DEF:mydll64.def
And this is the D program.
testdll64d.d

}
--
Output:

I am concerned that it hasn't been answered only because it is in a less popular sub forum. I'll try to make it short. This websites recommends implib for the creation of import library therefore I have been using it. When I compile + link my code containing extern( Windows ) function declarations, I get the following messages: Error 42: Symbol Undefined _functionName@ordinal (generic case) Error 42: Symbol Undefined _glGetIntegerv@8 (just an example) Let's hypothesize that I am using shared.dll and I would like to statically link against it using an import library. I use this command: implib /noi /system shared.lib ..\shared.dll To generate the import library. Once done, I make sure the linker finds it and rebuild the program. I get the same errors. Hello Phil Lavoie. Yes, sometimes implib works and sometimes it doesn't. Please check http://blogs.msdn.com/b/oldnewthing/archive/2006/07/27/679634.aspx The fact that names in import libraries are decorated means that it is doubly crucial that you use the official import library for the DLL you wish to use rather than trying to manufacture one with an import library generation tool. As we noted earlier, the tool won't know whether the ordinal assigned to a named function was by design or merely coincidental. But what's more, the tool won't know what decorations to apply to the function (if the name was exported under an undecorated name). Consequently, your attempts to call the function will fail to link since the decorations will most likely not match up. Therefore, I looked into the import library only to find that no exported symbols have and ordinal appended (@someInt), CONTRARILY to the symbols you can find in the import library provided by the compiler (..\D\windows\lib\*). ..@someInt is actually called a 'decoration'. So... how were those generated in the first place (what makes them have those ordinals, was this an automated process or did someone actually wrote the module definition files by hand)? I can't give you an exact answer (I'm not from Digital Mars :)), but I believe they used http://www.digitalmars.com/ctg/coffimplib.html against the official .libs from the Windows SDK. Writing .def by hand is also an option. How and why is extern( Windows ) generating symbol calls expecting ordinals for stdcall conventions (how does it know that _glGetIntegerv has an ordinal of 8 for example)? Is the ordinal a desirable requirement for those calls? From http://msdn.microsoft.com/en-us/library/zxk0tw93(v=vs.71).aspx An underscore (_) is prefixed to the name. The name is followed by the at sign (@) followed by the number of bytes (in decimal) in the argument list. Therefore, the function declared as int func( int a, double b ) is decorated as follows: _func@12 Conclusion If you have the shared.dll only, try 'implib' or 'implib /system'. This may not work if the .dll contains stdcall functions exported as 'undecorated'. If you have the official shared.lib, try coffimplib. If you have both shared.dll and shared.h, you can write a module definition file by hand.

Not bad. Is it written in D? It started as a D project, then I've moved it to C. A few notes: - It's much faster to just pass all the files to dmd at once and compile/link all in one step. So, instead of this: dmd -wi -c a.d -ofoutput\a.d dmd -wi -c b.d -ofoutput\b.d dmd -ofa.exe output\a.obj output\b.obj Just do this: dmd -wi -ofa.exe -odoutput a.d b.d It's a lot faster, plus in my experience compiling separately can sometimes lead to linking problems (somehting to do with how dmd handles templates, I think). Understood. - To support things like ldc, gdc and dvm (via ldmd, gdmd, dvm-current-dc.bat, etc...), the config file should take a path to the actual exe or bat (such as dmd.exe) the users wants to run, instead of just the path to dmd.exe. So like dmd_path=C:\D\dmd2\windows\bin\dmd.exe insetad of dmd_path=C:\D\dmd2\windows\bin The project file is actually a GNU makefile with special variables. I'll see how can I make a makefile that supports multiple compilers and compile/link in one step. - The first couple times I made a new project I got some error about it not being able to copy a template. But then it seemed to work ok anyway. I don't remember exactly what it said, and it doesn't seem to be happening anymore (don't know why) so I can't check. It happens when either the destination file already exists, or when the template file is missing. I'll add a more descriptive message. - It *seems* to start up with a default blank project, but you can't use it. You still have to go to File-New project. That's a little confusing. - It'd be good to be able to select and copy the text in the compilation panel at the bottom. - It'd be intuitive to be able to add files to a project by right-clicking D source files or whatever and then have Add file(s)... in a drop-down menu. - More features and configurability with both building and interface would be nice to have in later versions, ie more bells and whistles ;) Right. I'll improve it as time permits. I love that the interface is super-fast, light on memory, and uses the native system controls. And the automatic build management and Help links are really nice to have. Thanks for the feedback!

D strings are not null-terminated, so v[5] = 0 doesn't do
anything to
terminate that string. The whole point of toStringz is to put a
null character
on the end of a string (and allocate a new string if need be)
and return a
pointer to it. C code will then use the null character to
indicate the end of
the string, but D won't.
What you've done with
string s = toUTF8(v) ~ , world!;
is create a string that is
['H', 'e', 'l', 'l', 'o', '\0', '\0', '\0', ...] (all of the
characters up to
the v[99] are '\0')
and append
[',', ' ', 'w', 'o', 'r', 'l', 'd', '!']
to it. The result is a string whith is 108 characters long with
a ton of null
characters in the middle of it. When you call toStringz on it,
it may or may
not allocate a new string, but in the end, you have a string
which is 109
characters long with the last character being '\0' (still with
all of the null
characters in the middle) which you get an immutable char*
pointing to.
So, when the C code operates on it, it naturally stops
processing when it hits
the first null character, since that's how C determines the end
of a string.
You can embed null characters in a string and expect C to
operate on the whole
thing. And since D strings aren't null-terminated, you can't
expect that
setting any of it their elements to null will do anything to
terminate the
string in D or stop D functions from operating on the whole
string. You have
to slice the static wchar array with the exact elements that
you want if you
intend to terminate it before its end.

You can always use the functions you would use in C.
You can see your language id in this page:

Example
-

import std.c.windows.windows;

extern (Windows) LCID GetSystemDefaultLCID();
int main()
{
LCID lcid = GetSystemDefaultLCID();
printf(GetSystemDefaultLCID = 0x%04X\n, lcid);
switch (lcid)
{
case 0x0409:
writeln(United States (US));
break;
case 0x040c:
writeln(France (FR));
break;
default:
writeln(Unknown);

You can try

_mysql_init@4=mysql_init
//
// --- mysqltest.d
import libmysql;

// --- libmysql.di ---

export extern (Windows) MYSQL *mysql_init(MYSQL *);

$ implib /system libmysql.lib libmysql.def
