| void firevision::SharedMemoryImageBufferLister::print_footer | ( | ) | [virtual] |
Print footer of the table.
This should fit on the terminal and thus have a width of at most 79 columns.

Print info about segment.
This method is called for every matching shared memory segment. You should print a line of information (maybe more than one line if needed) about the segment.
- Parameters:
-
header The data-specific header shm_id The id of the shared memory segment semaphore Semaphore key of the given shared memory segment mem_size the total memory size memptr pointer to the data segment.

| void firevision::SharedMemoryImageBufferLister::print_no_orphaned_segments | ( | ) | [virtual] |
Print this if no matching orphaned segment was found.
Called by SharedMemory::erase_orphaned() if no matching segment could be found.
Implements fawkes::SharedMemoryLister.
