Member Function Documentation

◆ print_footer()

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.

Implements fawkes::SharedMemoryLister.

Definition at line 960 of file shm_image.cpp.

◆ print_header()

void firevision::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 946 of file shm_image.cpp.

◆ print_info()

void firevision::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
headerThe data-specific header
shm_idThe id of the shared memory segment
semaphoreSemaphore key of the given shared memory segment
mem_sizethe total memory size
memptrpointer to the data segment.

Implements fawkes::SharedMemoryLister.

◆ print_no_orphaned_segments()

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.

Definition at line 973 of file shm_image.cpp.

◆ print_no_segments()

void firevision::SharedMemoryImageBufferLister::print_no_segments ( )
