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?

set         


        

Answer 1

This conversion is safe if you are filling same value in all 4 bytes. If byte order matters then this conversion is not safe. Because when you use integer to fill 4 Bytes at a time it will fill 4 Bytes but order depends on the endianness.
