Hi.
I have code for reading and writing gds files that I have inherited from
a company and need to make standards compliant. Unfortunately the code
is heavily dependant on the win api. I think I can get around
everything but one stumbling point I would like some advice on.
The win api uses an unsigned char array for writing binary data to and
from the gds file. Now, one reason I want standards compliant code is
to be able to run my...

Does anybody know why
unsigned char myImage; works but
unsigned char myImage; does not?
I think its because the second line is a value too big for unsigned
char, is this correct?
If so:

I have a managed DLL that I've used to expose a C++ class. One of the
functions in this class reads a line out of a file into a buffer of type
"unsigned char*". Since all the data is just straight byte data (that is,
I'm concerned with individual bits packed into the bytes), I'd like to put
that data into a byte array that's passed from the C# app to the DLL
function.
In the past, I've been able to marshal strings to character strings...

I'm trying to use a C++ .lib from C# (I tried the Interop group will no
results).
I have a working wrapper DLL (I can get back simple things like int), but
I'm having issues dealing with an array of bytes.
For example, the .lib contains this function:
int create(int id, int scale, unsigned char *image);
In the wrapper DLL I have this function:

Hi.
I'm in the process of making a GUI for a function someone else wrote,
and i've come across a type i'm unfamiliar with, namely
"std::vector<unsigned char>". I need to get the contents of this
variable into a form I can display in a text box, but i'm not sure what
to expect inside of the variable, whether I can just treat it like an
array e.t.c. Any help would be appreciated.
Thanks,

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...
