NAME
kcopy —
copy data with abort on page
fault
SYNOPSIS
#include
<sys/systm.h>
int
kcopy(const
void *src, void
*dst, size_t
len);
DESCRIPTION
kcopy()
copies len bytes from src to
dst, aborting if a fatal page fault is encountered.
kcopy()
must save and restore the old fault handler since it is called by
uiomove(9), which may be in the path of servicing a non-fatal page
fault.
RETURN VALUES
kcopy() returns 0 on success and an error
number on failure.
