xcp(1) hxtools xcp(1) Name xcp -- proof-of-concept cp(1) with alternate copying mechanisms Syntax xcp [-d] [-m|--mmap] [-s|--splice] fromfile tofile Description Copies the file from src to dst using mmap(2) or splice(2) instead of the read(2)-write(2) cycle that is normally used. mmap may actually be faster than the r/w cycle. Options -d Calls mmap(2) on both the source and destination, and does a mem- cpy(3). -m, --mmap Calls mmap(2) on the source and uses write(2) for the destination. -s, --splice Calls splice(2) on a pipe(2) pair. This is silly, but it is what it is because splice(2) does not support file-to-file transfers. hxtools 2008-11-11 xcp(1)
