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 have a piece of code that needs to read the contents of a binary file
(that I've created with another app) into an array of structures. The
binary data in the file represents just a series of singles that
correspond to those in my structure detailed below. So when I load the
file, all that I know for certain is that there will be some multiple
of these eight singles represented in the binary data.
My code below will read the data...

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?

I want to marshal a structure containing a variable length array which will be populated within a C++ dll. the structure is the following
Public Structure myStructure{
Public int size;
Public myInsideStructure inside;
};
The myInsideStructure just contains a string. The problem is the size of the myInsideStructure wont be known until runtime and the size variable will have the number of posts in the myInsideStructure structure...

I have operation within a class that marshals the data into a byte
array. Below are three different ways that work. Are there any
downsides to using one over the the other?
public virtual byte ToRaw1()
{
byte byteArray = new byte;
IntPtr pointer = Marshal.AllocHGlobal(Size);
Marshal.StructureToPtr(this, pointer, false);
Marshal.Copy(pointer, byteArray, 0, Size);

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...

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,...
