- process contract status functions
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);
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().
Upon successful completion, ct_pr_status_get_param(), ct_pr_status_get_fatal(), ct_pr_status_get_members(), and ct_pr_status_get_contracts() return 0. Otherwise, they return a non-zero error value.
The ct_pr_status_get_param(), ct_pr_status_get_fatal(), ct_pr_status_get_members(), and ct_pr_status_get_contracts() functions will fail if:
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(), and ct_r_status_get_contracts() functions will fail if:
The requested data were not available in the status object.
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.
