I am coding a managed C# wrapper for an unmanaged C DLL and I am unable to
marshal a structure that contains an array of structures. When executed, the
following code throws an ArgumentException with a description “Type
ErrorInjectionBuffer can not be marshaled as an unmanaged structure; no
meaningful size or offset can be computed.” I have also included snippets
from the .H file. Any assistance would be greatly appreciated.

Can anyone suggest how I would marshal a variable length structure back from
an API call. Specifically, I am looking at the WaitForDebugEvent function,
which returns a DEBUG_EVENT structure.
However, the DEBUG_EVENT structure is defined as a union, and the size and
contents vary depending on the event code contained in the header.
typedef struct _DEBUG_EVENT {
DWORD dwDebugEventCode;
DWORD dwProcessId;

I want to pass a managed c# byte (8 bit) array into a unmanaged c++
function:
extern "C" void AddData(unsigned int* data);
I use P/Invoke on managed side to do the marshaling as following:
public static extern int AddData(IntPtr data);

Hi,
I'm working with Marshalling. I got an idea to pass an object to the
Native side as a byte array i.e. as void* in terms of C.
For example:
I have a .NET structure Point that contains two fields X and Y that
means that the byte array representation will look in the memory like
this: "XXXXYYYY" First four bytes are X and second for bytes are Y.

When using Marshal to copy data from a byte array to the structure
below, only the first byte of the "other" array is getting copied from
the original byte array. What do I need to specify to get
Marshal.PtrToStructure to copy the all the data into the "other"
array?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
