KVM_READ(3)		 BSD Library Functions Manual		   KVM_READ(3)

NAME
     kvm_read, kvm_write — read or write kernel virtual memory

LIBRARY
     Kernel Data Access Library (libkvm, -lkvm)

SYNOPSIS
     #include <kvm.h>

     ssize_t
     kvm_read(kvm_t *kd, unsigned long addr, void *buf, size_t nbytes);

     ssize_t
     kvm_write(kvm_t *kd, unsigned long addr, const void *buf, size_t nbytes);

DESCRIPTION
     The kvm_read() and kvm_write() functions are used to read and write ker‐
     nel virtual memory (or a crash dump file).	 See kvm_open(3) or
     kvm_openfiles(3) for information regarding opening kernel virtual memory
     and crash dumps.

     The kvm_read() function transfers nbytes bytes of data from the kernel
     space address addr to buf.	 Conversely, kvm_write() transfers data from
     buf to addr.  Unlike their SunOS counterparts, these functions cannot be
     used to read or write process address spaces.

RETURN VALUES
     Upon success, the number of bytes actually transferred is returned.  Oth‐
     erwise, -1 is returned.
