kvm_nlist(3KVM) 					    Kernel VM Library Functions 					   kvm_nlist(3KVM)

NAME

       kvm_nlist - get entries from kernel symbol table

SYNOPSIS

       cc [ flag... ] file... -lkvm [ library...]
       #include <kvm.h>
       #include <nlist.h>

       int kvm_nlist(kvm_t *kd, struct nlist *nl);

DESCRIPTION

       The  kvm_nlist()  function examines the symbol table from the kernel image identified by kd (see kvm_open(3KVM)) and selectively extracts a
       list of values and puts them in the array of nlist structures pointed to by nl. The name list pointed to by nl  consists  of  an  array	of
       structures containing names, types and values.  The n_name field of each such structure is taken to be a pointer to a character string rep-
       resenting a symbol name.  The list is terminated by an entry with a null pointer (or a pointer to a null string) in the n_name field.   For
       each  entry  in	nl,  if  the  named  symbol is present in the kernel symbol table, its value and type are placed in the n_value and n_type
       fields. If a symbol cannot be located, the corresponding n_type field of nl is set to 0.

RETURN VALUES

       The kvm_nlist() functions returns the value of  nlist(3UCB) or nlist(3ELF), depending on the library used.

kvm_read(3KVM)						    Kernel VM Library Functions 					    kvm_read(3KVM)

NAME

       kvm_read, kvm_write - copy data to or from a kernel image or running system

SYNOPSIS

       cc [ flag... ] file... -lkvm [ library...]
       #include <kvm.h>

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

       ssize_t kvm_write(kvm_t *kd, uintptr_t addr, void *buf, size_t nbytes);

DESCRIPTION

       The  kvm_read()	function  transfers  data  from the kernel image specified by kd (see kvm_open(3KVM)) to the address space of the process.
       nbytes bytes of data are copied from the kernel virtual address given by addr to the buffer pointed to by buf.

       The kvm_write() function is like kvm_read(), except  that  the  direction  of  data  transfer  is  reversed.  To  use  this  function,  the
       kvm_open(3KVM)  call  that  returned kd must have specified write access. If a user virtual address is given, it is resolved in the address
       space of the process specified in the most recent kvm_getu(3KVM) call.

USAGE

       The kvm_read() and kvm_write() functions are obsolete  and  might  be  removed  in  a  future  release.	The  functions	described  on  the
       kvm_kread(3KVM) manual page should be used instead.

RETURN VALUES

       On success, these functions return the number of bytes actually transferred. On failure, they return -1.
