#  FILE   : sendfile
#
#  PURPOSE: Copy files from server to client using the sendfile()
#           function.
#           
#
#  SETUP: The home directory of root on the machine exported as "RHOST"
#         MUST have a ".rhosts" file with the hostname of the client 
#         machine, where the test is executed. 
#
#  HISTORY:
#    06/09/2003 Manoj Iyer manjo@mail.utexas.edu
#    - Modified to use LTP APIs, and added check to if commands used in test
#    exists.
