One last sub question, is this a good way to make programs in C by
defining a struct and assign function pointers to it to make it look
like a oo.
No. C has a different paradigm, trying to write python using C syntax
as bad an idea as trying using German sentence structure English to
write is.
>Or are there other recommended methods to make a program.
I recommend learning C as a language on its own, and trying to forget
how you might do something in a different language. It will only
confuse you and lead to very inefficient code.

Personally, I think it looks messy, overcomplicated and prone to
errors. C is not C++ or python or Java. I strongly recommend you write
C like C.

Why malloc? Why a memory leak?

Why malloc?
In C, what else would you use to allocate memory than one of the
*alloc family?

void leak(size_t howmuch) {
malloc(howmuch) ;

will do it nicely, provided you #include <stdlib.h>

What about putting the object on the stack? In C you do not
dynamically allocate memory unnecessarily.

In standard C there is no such thing as a stack, and no mechanism
for placing run-time sized objects in automatic storage space.

I was referring to memory allocation, as opposed to automatics. The
latter aren't dynamic.
In C you do not dynamically allocate memory unnecessarily.
Why not?

Unless you can find a suitable C99 implementation and use VLAs.

Is there a general way of injecting code into a function, typically
before and/or after the existing code ? I know that for most purposes,
an OO solution, such as the template pattern, is a cleaner way to get

control over the design and you are given a function to start with). In
particular, I want to get access to the function's locals() just before
it exits, i.e....
