Solaris 10:
  f% man splice
  No manual entry for splice
Mac OS X 10.5.4
  m% man splice
  No manual entry for splice
Linux 2.6.23...
  o% man splice

  one of the descriptors MUST refer to a pipe.

So of the three tolerably current "UNIX" systems available
to me, two of them don't have it, and the third seems to be
saying you cannot use it to move data from a file (which is
not a pipe) to a socket (which is not a pipe), which is the
use-case for sendfile().
