NAME

6       fvshmem - List and cleanup FireVision image shared memory segments
7

SYNOPSIS

9       fvshmem [-h] [-c] [-c[t]] [-l] [-m] [-i image_id file]
10

DESCRIPTION

12       List, save, or cleanup shared memory segments created by FireVision.
13       FireVision stores images retrieved from cameras and lookup tables in
14       shared memory segments. Olugins can decide to create additional
15       segments. All shared memory segments have a unique ID.
16
17       A list of currently existing segments can be retrieved. For images a
18       snapshot can be written into a FireVision raw file. Segments might
19       require cleanup if the creating process has died without closing the
20       segments. You can also choose to cleanup segments of specified types.
21       Segments for which are currently used are detected and not removed.
22

OPTIONS

24       -h
25           Show usage instructions.
26
27       -l
28           List FireVision shared memory segments.
29
30       -c[t]
31           Cleanup shared memory segments. A type t can be optionally passed
32           to determine that only these segments should be cleaned up. The
33           type can be either i for images or l for lookup tables. If empty
34           both types are cleaned up.
35
36       -i image_id file
37           Read the file from the shared memory image segment with the ID
38           image_id and write it to file as FireVision raw.
39
