Setting a buffer of char* with intermediate casting to int*

Question

I could not fully understand the consequences of what I read here: Casting an int pointer to a char ptr and vice versa

In short, would this work?

Answer 1

In addition to the endian issue, which has already been mentioned here:

CHAR_BIT - the number of bits per char - should also be considered.

It is 8 on most platforms, where for (int i=0; i<4; i++) should work fine.

A safer way of doing it would be for (int i=0; i.

Alternatively, you can include and use for (int i=0; i<32/CHAR_BIT; i++).
