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...

What is the best way to read data from a file into a fixed size array of
unsigned char? This is a file holding only a SHA1 digest. What I would
really like to do is initialize the ifstream with the buffer allocated to
hold the data, seekg(ios_base::end) and magically have the data appear in
the buffer. I believe something close to this can...

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...

hi
got a little prob with data types.
I´m reading data from a socket in to a unsigned char buf; .
Now, lets say there are 60Bytes written into the array( but it is
always different).
Now i want to give the bytes to a other class like:
pushControlPacket(buf);

Hello,
Early on I decided that all text (what most people call "strings" )
in my code would be unsigned char *. The reasoning is that the elements
of these arrays are decidedly not signed. In fact, they may not even
represent complete characters. At this point I think of text as simple
binary blobs. What charset, character encoding and...

Hi,
can anybody with ctypes experience tell me, how to handle a C function
that returns an unsigned char*? Obviously it is not a restype of
c_char_p.
Best regards,

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. ...
