.Sh DESCRIPTION
|
|
.Fn kvm_getfiles
|
|
returns a (sub-)set of the open files in the kernel indicated by
|
|
.Fa kd.
|
|
The
|
|
.Fa op
|
|
and
|
|
.Fa arg
|
|
arguments constitute a predicate which limits the set of files
|
|
returned. No predicates are currently defined.
|
|
.Pp
|
|
The number of processes found is returned in the reference parameter
|
|
.Fa 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.
|
|
.Sh RETURN VALUES
|
|
.Fn kvm_getfiles
|
|
will return NULL on failure.
|
|
.Pp
|
|
.Sh BUGS
|
|
This routine does not belong in the kvm interface.
