Hi!
I'm working on a library written in D.
After some tests I have discovered that my library leaks memory, those leaks
are caused by dynamics array that I use in my library.
Does it 'leak'? What is your exact setup, why isn't the GC collecting
that memory?
My question is:
Should dynamics array be deallocated automatically when a procedure returns?
There is another way to acomplish this?
Maybe I'm doing something wrong, so, I post the function that causes the leak:
public string getWindowText(HWND hWnd)
{
int len = GetWindowTextLengthW(hWnd);
wchar[] t = new wchar[len + 1]; // How to deallocate this?
GetWindowTextW(hWnd, t.ptr, len);
/*
* I'm converting the wchar[] to char[],
* the variable 't' should be deallocated
* because I not need it anymore.
*/
return to!(string)(t[0..len]);
}
Unless the string gets extremely long, you could allocate it on the stack:
wchar[] t=(cast(wchar*)alloca(wchar.sizeof*(len+1)))[0..len+1];
