/*---------------------------------------------------------------------------
Automated search for EFAULT in the following DMAPI commands:
   dm_get_allocinfo
   dm_get_config
   dm_get_config_events
   dm_getall_dmattr
   dm_init_attrloc

There are other EFAULT tests, in the programs that test individual 
DMAPI functions.  Those other tests are referenced in comments in this source.

The command line is:
   test_efault [-s sid] [-v] ls_path pathname

where:
   sid
      is the session ID whose events you you are interested in.
   ls_path
      is the path to a copy of ls, which will be copied as a test file.
   pathname
      is the filesystem to use for the test.
