Re: including sys/malloc.h produces errors?

If you are writing a user-mode component (== chunk o' code), then you
typically do *not* want to include headers from 'sys'. That directory
contains kernel-related headers.

If you are including it because your library accesses kernel structures
in some way, then you should include <sys/types.h> before
<sys/malloc.h>.

I am in the process of converting code that uses malloc.h to include
stdlib.h instead. It provides the prototype OK.
Is that the right thing to do?

anyone else seen this? stuck in the mud...

There is no 'malloc.h' for user-mode code. It's an out-of-date file
that persists in some systems, and is not present in Darwin/Mac OS X.
