   4  *  @file    Missing_Svc_Conf_Test.cpp
   5  *
   6  *  A test to ensure that service_config::open() returns -1 if it is
   7  *  fully defaulted, but no default svc.conf file exists. The first
   8  *  test verifies that open returns -1 with errno ENOENT. A second
   9  *  test ensures that service_config::open() returns 0 when any
  10  *  explicit directive is supplied by the command line, regardless
  11  *  of the existence of default svc.conf.
  12  *
  13  *  Presently there is no svc.conf file in the tests directory and
  14  *  this test relies on that. It is assumed that this will stay
  15  *  true, since adding a default svc.conf file in this directory my
  16  *  impact other tests.
