kcopy —
#include <sys/systm.h>
int
  
  kcopy(const
    void *src, void
    *dst, size_t
  len);
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.
kcopy() returns 0 on success and an error number on
  failure.
