KVMREAD(3) BSD Library Functions Manual KVMREAD(3)

NAME
     kkvvmmrreeaadd, kkvvmmwwrriittee - read or write kernel virtual memory

SYNOPSIS
     ##iinncclluuddee <>

     ssizet
     kkvvmmrreeaadd(kvmt *kd, ulong addr, void *buf, sizet nbytes);

     ssizet
     kkvvmmwwrriittee(kvmt *kd, ulong addr, const void *buf, sizet nbytes);

DESCRIPTION
     The kkvvmmrreeaadd() and kkvvmmwwrriittee() functions are used to read and write ker-
     nel virtual memory (or a crash dump file). See kkvvmmooppeenn(3) or
     kkvvmmooppeennffiilleess(3) for information regarding opening kernel virtual memory
     and crash dumps.

     The kkvvmmrreeaadd() function transfers nbytes bytes of data from the kernel
     space address addr to buf.  Conversely, kkvvmmwwrriittee() 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.
