46.Sh LIBRARY

48.Sh SYNOPSIS
49.In sys/types.h
50.In kvm.h
51.Ft char *
52.Fn kvm_getfiles "kvm_t *kd" "int op" "int arg" "int *cnt"
53.Sh DESCRIPTION
54.Fn kvm_getfiles
55returns a (sub-)set of the open files in the kernel indicated by
56.Fa kd .
57The
58.Fa op
59and
60.Fa arg
61arguments constitute a predicate which limits the set of files
62returned.  No predicates are currently defined.
63.Pp
64The number of files found is returned in the reference parameter
65.Fa cnt .
66The files are returned as a contiguous array of file structures,
67preceded by the address of the first file entry in the kernel.
68This memory is owned by kvm and is not guaranteed to be persistent across
69subsequent kvm library calls.  Data should be copied out if it needs to be
70saved.
71.Sh RETURN VALUES
72.Fn kvm_getfiles
73will return NULL on failure.
