Subject: Why do the rh_alloc functions return a pointer?
Date: Thu, 15 Feb 2007 13:29:10 -0600 [thread overview]
Message-ID: <45D4B486.7030409@freescale.com> (raw)
The rh_alloc functions (rh_alloc, rh_alloc_fixed, rh_alloc_align) all return a
"void *". However, the actual value passed is an offset into a block of memory.
In most cases, the first time rh_alloc is called, it returns zero.
There are several wrapper functions for rh_alloc, and all of them cast the
return value to an unsigned integer.
So my question is, why do the rh_alloc functions return a pointer? Shouldn't
they all return a u32 or uint?
