# mmap test purpose

# __stc_assertion_start
#
# ID: mmap_007
#
# DESCRIPTION:
#       Verify compatibility between open(O_RDWR) &
#	  mmap(PROT_READ|PROT_WRITE, MAP_PRIVATE)
#
# STRATEGY:
#       1. run "mount -F smbfs //server/public /export/mnt"
#       2. mkfile in smbfs & local dir, with the same size
#	3. open(O_RDWR) & mmap(PROT_READ|PROT_WRITE, MAP_PRIVATE) the smbfs file
#	4. read data from the local file and write into the smbfs file
#	4. diff the smbfs file before written & after written
# KEYWORDS:
#
# TESTABILITY: explicit
#
