NAME
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_sta- tus_get_svc_aux, ct_pr_status_get_svc_ctid, ct_pr_status_get_svc_creator - process contract status functions
SYNOPSIS
cc [ flag... ] file... -D_LARGEFILE64_SOURCE -lcontract [ library... ] #include <libcontract.h> #include <sys/contract/process.h> int ct_pr_status_get_param(ct_stathdl_t stathdl, uint_t *paramp); int ct_pr_status_get_fatal(ct_stathdl_t stathdl, uint_t *eventsp); int ct_pr_status_get_members(ct_stathdl_t stathdl, pid_t **pidpp, uint_t *n); int ct_pr_status_get_contracts(ct_stathdl_t stathdl, ctid_t **idpp, uint_t *n); int ct_pr_status_get_svc_fmri(ct_stathdl_t stathdl, char **fmri); int ct_pr_status_get_svc_aux(ct_stathdl_t stathdl, char **aux); int ct_pr_status_get_svc_ctid(ct_stathdl_t stathdl, ctid_t *ctid); int ct_pr_status_get_svc_creator(ct_stathdl_t stathdl, char **creator);
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. Other- wise, 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_sta- tus_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. The ct_pr_status_get_param(), ct_pr_status_get_fatal(), ct_pr_status_get_members(), ct_r_status_get_contracts(), ct_pr_sta- tus_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: ENOENT The requested data were not available in the status object.
EXAMPLES
Example 1 Print members of process contract 1. Open the status file for contract 1, read the contract's status, obtain the list of processes, print them, and free the status object. #include <sys/types.h> #include <fcntl.h> #include <libcontract.h> #include <stdio.h> ... int fd; uint_t i, n; pid_t *procs; ct_stathdl_t st; fd = open("/system/contract/process/1/status"); ct_status_read(fd, &st); ct_pr_status_get_members(st, &procs, &n); for (i = 0 ; i < n; i++) printf("%ld\n", (long)procs[i]); ct_status_free(stat); close(fd); ...
