 Posted: Thu Jul 22, 2004 6:40 pm Post subject: bug in win32.winnt |
 |
|
The following code doesn't compile:
| Code: |
import win32.winnt;
void main()
{
TOKEN_PRIVILEGES tkp; // pointer to token structure
tkp.Privileges.length = 1;
}
|
dmd reports: "core32\win32\winnt.d(31): *(#tkp + 4).length is not an lvalue".
I'm using a somewhat old version which requires -d to compile (C casts).
With the most recent version of Y Tomino's headers, I get the same but on line 24. |

I've isolated the problem and I think I even understand it: You're not allowed to change the length of the array of struct LUID_AND_ATTRIBUTES. The compiler just says you can't do that.
I don't think there's anything wrong with Core32 and I think the only problem with DMD is an unclear error message. Maybe we should ask Walter for a message like this "you can't adjust the length of an element within a struct."
| Code: | struct LUID_AND_ATTRIBUTES {
int Attributes;
}
struct TOKEN_PRIVILEGES {
int PrivilegeCount;
LUID_AND_ATTRIBUTES Privileges[1000];
}
void main()
{
TOKEN_PRIVILEGES tkp; // pointer to token structure
tkp.Privileges.length = 1;
} |
(I changed things around to make the error easier to duplicate, but the concept should be the same.) |

| The thing is that the code should work: I took it from a MSDN docs example. I was manually adding to my file the declarations I needed, but I decided I could use one of those two, but both fail... I'll have to go back to manual instead of auto. |

Well, I don't know what to tell you. Assuming Mike shows up and agrees to change Core32, what exactly would you have him change? Turn the rectangular array into a dynamic array? That sounds dangerous.
I don't know what MSDN example you're referring to, but I'd suggest that maybe you're misinterpreting it. Or maybe C++ allows squirrelly behavior here, but D doesn't. Maybe dm.D.bugs bug report is needed. |

My mistake there: the MSDN example doesn't have the length assignment.

That wouldn't be needed: the length of the array is 1, which works great for what I needed.

Misinterpretation. 100?.
Bug report posted, btw. |

Yeah, I already noticed the bug report in dm.D.bugs. Hopefully, it helps out Walter. |

if this is still important, post here, I'm about to get Core32 D 2.0 ready ....
so might look at this if I can, I think that you are missing the underlying C-ness of the Win32 API. and a simple wrapper class is what you need to give you the illusion of what you seem to want .... |
