kvm_getfiles(3)

NAME

kvm_getfiles - survey open files

LIBRARY

Kernel Data Access Library (libkvm, -lkvm)

SYNOPSIS

#include <kvm.h>
#include <sys/types.h>
#define _KERNEL
#include <sys/file.h>
#undef _KERNEL
char *
kvm_getfiles(kvm_t *kd, int op, int arg, int *cnt);

DESCRIPTION

The kvm_getfiles() function 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 files found is returned in the reference pa

rameter cnt.
The files are returned as a contiguous array of file struc

tures, 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

The kvm_getfiles() function will return NULL on failure.
