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.

) | [virtual] |
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.
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. |
