Hi, hope there's someone here who can help me with this problem


I want to use some functions like "GetSystemDirectory" and something like that but I get error when I use them.


Here a sample code :

import win32.windows;

int main(char[][] args)
{
LPSTR test = null;
GetSystemDirectoryA(test,256U);
return 0;
}


When I run it I get "objet.Error - Access violation".

What am I doing wrong or what is wrong with the binding ?


(Information : I'm using D2 [dmd2.048] with latest phobos library and latest win32 binding)



EDIT : Ok I found what I was doing wrong but it seems that there's another problem again :

import std.stdio;
import std.string;
import win32.windows;

int main(char[][] args)
{
LPSTR test = cast(char*)"";
try
{
GetSystemDirectoryA(test,500U);
printf("%s", test);
}
catch(Object o)
writeln(o.toString);
return 0;
}


Which prints "indows\system32"
Why I don't have "C:\Windows\system32" ?

Ok, I tried with writeln and it's ok now

So, this code works well now :



import std.stdio;
import std.string;
import std.conv;
import win32.windows;

int main(char[][] args)
{
LPSTR test = cast(char*)"";
try
{
uint i = GetSystemDirectoryA(test,100U);
writeln(to!string(test));
}
catch(Object o)
writeln(o.toString);
return 0;
}
