 * arguments are all pointers; by name they are:

 *	copy_str - a function or macro invoked as copy_str(dst,src,maxlen)
 *	    that has strlcpy or memcpy semantics; the destination is
 *	    pre-filled with zeros; for libkvm, src is a kvm address
 *	p - source struct proc

 *	uc - source struct ucreds

 *	paddr - kernel address of the source struct proc
 *	praddr - kernel address of the source struct process
 *	sess - source struct session
 *	vm - source struct vmspace
 *	lim - source struct plimits
 *	sa - source struct sigacts
 * There are some members that are not handled by these macros

 * p_tpgid, p_tsess, p_vm_rssize, p_u[us]time_{sec,usec}, p_cpuid
