What does "suitable aligned for storage of *any* type of object" means?
On some platforms, it is either desirable or required that, say, a
8-byte double is stored at a memory location which is is also aligned to
8-bytes:
Oh, it was told for different architectures. It's quite clear for me now.
What is pointer coercion? I have no pointer before malloc() returns.
Right. Well, malloc returns a (void *), but most people want to use the
memory malloc returns to hold their own arrays, structs, whatever, which
means that you need to be able to coerce the (void *) malloc gave you
into whatever pointer type you want to actually use.
So the memory malloc gives you needs to be aligned so that it's OK to be
used for even the most restrictive datatype known to the system,
commonly 8, 16, or 32 bytes.
Pointer coercion means a type cast? I see now.
I read it as 'force change of pointer value' before.
Thanks, guys!
