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. |
