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
	      memcpy(3).

       -m, --mmap
	      Calls mmap(2) on the source and uses write(2) for	 the  destina-
	      tion.

       -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.
