I am working on some tricky code and need some help from the experts.
I have several large data structures (uBLAS matrices) that must be written
to a pre-allocated (by another program) chunk of static memory. Currently
our code emulates this behavior using BOOST::serialize archives. According
to the documentation, these archive objects will write to a given ostream.
We would like to define an ostream that writes to this address without...

Hello All,
I am relatively new to C programming and I am struck with a problem in
dynamic memory allocation.
I would like to know if it is ok to pass the 'memory address' returned
by malloc()(stored not in a pointer variable but as an element of an
array of type int*) directly to free(). My program allocating and
freeing memory this way is corrupting the heap.
Can anybody guide me on this.
Thanks in advance

Hi everyone - I have a question. I am just playing around with C (I
realise there are better ways to do what I want, but I would like to
do it this way to increase my understanding of C) and would like to
read an executable file in to a portion of memory and then pass
execution to this and execute the file. However, I can not get it
working and my efforts have resulted in a Seg Fault.
Below is the code I have got
#include "stdio.h"

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
