void 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.

Implements fawkes::SharedMemoryLister.

Definition at line 850 of file shm_image.cpp.

void SharedMemoryImageBufferLister::print_header (  )  [virtual]

Print header of the table.

This should fit on the terminal and thus have a width of at most 79 columns.

Implements fawkes::SharedMemoryLister.

Definition at line 836 of file shm_image.cpp.

void SharedMemoryImageBufferLister::print_info ( const fawkes::SharedMemoryHeader *  header,
int  shm_id,
int  semaphore,
unsigned int  mem_size,
const void *  memptr 
) [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.

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 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.
