I came across this piece of code, but am not able to entirely make sense of it:
(((x)[y] << 8) | (x)[(y)+1])
where x is a pointer to a const unsigned char and y is an integer.
It extracts the 16-bit big-endian value starting at index y from array x.

could anyone explain me please what does this piece of code mean?
int **d= (int**)malloc((m+1)*sizeof(int));
What are those ** for the d and the (int) ? Are they someway related to pointers?
int** d; //pointer to a pointer to an integer

I'd love to create some part dynamically. Would it be possible to use offsetof with string as a second argument? Something like:
offsetof( tic, "close.v");
Or can I convert char to member anyhow?
The offsetof construct is a compile time operation. It can't be used with anything that is generated dynamically.
