KCOPY(9) BSD Kernel Developer's Manual KCOPY(9)
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. kcopy() returns 0 on success and an error number on failure.
