NAME
kvm_getfiles —
survey open files
LIBRARY
Kernel Data Access Library (libkvm, -lkvm)
SYNOPSIS
#include <kvm.h>
#include <sys/kinfo.h>
#define _KERNEL
#include <sys/file.h>
#undef _KERNEL
char *
kvm_getfiles(
kvm_t
*kd,
int op,
int arg,
int *cnt);
DESCRIPTION
kvm_getfiles() returns a (sub-)set of the open files in the
kernel indicated by
kd. The
op and
arg arguments constitute a predicate which limits the
set of files returned. No predicates are currently defined.
The number of processes found is returned in the reference parameter
cnt. The files are returned as a contiguous array of
file structures, preceded by the address of the first file entry in the
kernel. This memory is owned by kvm and is not guaranteed to be persistent
across subsequent kvm library calls. Data should be copied out if it needs to
be saved.
RETURN VALUES
kvm_getfiles() will return
NULL
on
failure.
