DESCRIPTION
     These functions read  process  contract  status  information
     from a status object returned by ct_status_read(3CONTRACT).


     The ct_pr_status_get_param() function  reads  the  parameter
     set  term. The value is a collection of bits as described in
     process(4).


     The ct_pr_status_get_fatal() function reads the fatal  event
     set  term. The value is a collection of bits as described in

     process(4).


     The ct_pr_status_get_members() function obtains  a  list  of
     the  process  IDs  of the members of the process contract. A
     pointer to an array of process IDs is stored in *pidpp.  The
     number of elements in this array is stored in *n. These data
     are freed when the status object  is  freed  by  a  call  to
     ct_status_free(3CONTRACT).


     The ct_pr_status_get_contracts() function obtains a list  of
     IDs of contracts that have been inherited by the contract. A
     pointer to an array of IDs is stored in *idpp. The number of
     elements in this array is stored in *n. These data are freed
     when  the  status   object   is   freed   by   a   call   to
     ct_status_free().


     The                             ct_pr_status_get_svc_fmri(),
     ct_pr_status_get_svc_creator(),                          and
     ct_pr_status_get_svc_aux() functions read, respectively, the
     service  FMRI,  the  contract's  creator  execname  and  the
     creator's auxiliary field. The buffer pointed  to  by  fmri,
     aux  or  creator, is freed by a call to ct_status_free() and
     should not be modified.


     The ct_pr_status_get_svc_ctid() function reads  the  process
     contract id for which the service FMRI was first set.

RETURN VALUES
     Upon   successful   completion,    ct_pr_status_get_param(),
     ct_pr_status_get_fatal(),        ct_pr_status_get_members(),
     ct_pr_status_get_contracts(),   ct_pr_status_get_svc_fmri(),
     ct_pr_status_get_svc_creator(),  ct_pr_status_get_svc_aux(),
     and ct_pr_status_get_svc_ctid() return  0.  Otherwise,  they
     return a non-zero error value.

ERRORS
     The   ct_pr_status_get_param(),    ct_pr_status_get_fatal(),
     ct_pr_status_get_members(),    ct_pr_status_get_contracts(),
     ct_pr_status_get_svc_fmri(), ct_pr_status_get_svc_creator(),
     ct_pr_status_get_svc_aux(),  and ct_pr_status_get_svc_ctid()
     functions will fail if:

     EINVAL    The stathdl argument is  not  a  process  contract
               status object.

     Open the status file for contract  1,  read  the  contract's
     status,  obtain  the list of processes, print them, and free
     the status object.
