struct kinfo_file *

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. The value of
op describes the filtering predicate as follows:
Files associated with a process will include information about the process that has the file open.
KERN_FILE_BYFILE the recognized file
types are defined in
Only the first elemsize bytes of each array
entry are returned. If the size of the kinfo_file
structure increases in size in a future release of
OpenBSD, the kernel will only return the requested
amount of data for each array entry and programs that use
kvm_getfiles() will continue to function without the
need for recompilation.
The files are returned as a contiguous array of
kinfo_file structures. The number of structures found
is returned in the reference parameter cnt. This
memory is owned by kvm and will be overwritten by subsequent calls to
kvm_getfiles() and destroyed by
kvm_close(). Data should be copied out if it needs
to be saved.
kvm_getfiles() will return
NULL on failure.
kvm_getfiles() will fail if:
This routine does not belong in the kvm interface.
