NAME

These functions read process contract event information from an event object returned by ct_event_read(3CONTRACT) or ct_event_read_criti- cal(3CONTRACT). The ct_pr_event_get_pid() function reads the process ID of the process generating the event. The ct_pr_event_get_ppid() function reads the process ID of the process that forked the new process causing the CT_PR_EV_FORK event. The ct_pr_event_get_signal() function reads the signal number of the signal that caused the CT_PR_EV_SIGNAL event. The ct_pr_event_get_sender() function reads the process ID of the process that sent the signal that caused the CT_PR_EV_SIGNAL event. If the signal's sender was not in the same zone as the signal's recipient, this information is available only to event consumers in the global zone. The ct_pr_event_get_senderct function reads the contract ID of the process that sent the signal that caused the CT_PR_EV_SIGNAL event. If the signal's sender was not in the same zone as the signal's recipient, this information is available only The ct_pr_event_get_exitstatus() function reads the exit status of the process generating a CT_PR_EV_EXIT event. The ct_pr_event_get_pcorefile() function reads the name of the process core file if one was created when the CT_PR_EV_CORE event was gener- ated. A pointer to a character array is stored in *namep and is freed when ct_event_free(3CONTRACT) is called on the event handle. The ct_pr_event_get_gcorefile() function reads the name of the zone's global core file if one was created when the CT_PR_EV_CORE event was generated. A pointer to a character array is stored in *namep and is freed when ct_event_free() is called on the event handle. The ct_pr_event_get_zcorefile() function reads the name of the system-wide core file in the global zone if one was created when the CT_PR_EV_CORE event was generated. This information is available only to event consumers in the global zone. A pointer to a character array is stored in *namep and is freed when ct_event_free() is called on the event handle. RETURN VALUES
Upon successful completion, ct_pr_event_get_pid(), ct_pr_event_get_ppid(), ct_pr_event_get_signal(), ct_pr_event_get_sender(), ct_pr_event_get_senderct(), ct_pr_event_get_exitstatus(), ct_pr_event_get_pcorefile(), ct_pr_event_get_gcorefile(), and ct_pr_event_get_zcorefile() return 0. Otherwise, they return a non-zero error value. ERRORS
The ct_pr_event_get_pid(), ct_pr_event_get_ppid(), ct_pr_event_get_signal(), ct_pr_event_get_sender(), ct_pr_event_get_senderct(), ct_pr_event_get_exitstatus(), ct_pr_event_get_pcorefile(), ct_pr_event_get_gcorefile(), and ct_pr_event_get_zcorefile() functions will fail if: EINVAL The evthdl argument is not a process contract event object. The ct_pr_event_get_ppid(), ct_pr_event_get_signal(), ct_pr_event_get_sender(), ct_pr_event_get_senderct(), ct_pr_event_get_exitstatus(), ct_pr_event_get_pcorefile(), ct_pr_event_get_gcorefile(), and ct_pr_event_get_zcorefile() functions will fail if: EINVAL The requested data do not match the event type. The ct_pr_event_get_sender()a functions will fail if: ENOENT The process ID of the sender was not available, or the event object was read by a process running in a non-global zone and the sender was in a different zone. The ct_pr_event_get_pcorefile(), ct_pr_event_get_gcorefile(), and ct_pr_event_get_zcorefile() functions will fail if: ENOENT The requested core file was not created. The ct_pr_event_get_zcorefile() function will fail if: ENOENT The event object was read by a process running in a non-global zone. EXAMPLES
Example 1: Print the instigator of all CT_PR_EV_SIGNAL events. Open the process contract bundle. Loop reading events. Fetch and display the signalled pid and signalling pid for each CT_PR_EV_SIGNAL event encountered. #include <sys/types.h> #include <fcntl.h> #include <stdio.h> #include <libcontract.h> ... int fd; ct_evthdl_t event; pid_t pid, sender; fd = open("/system/contract/process/bundle", O_RDONLY); for (;;) { ct_event_read(fd, &event); if (ct_event_get_type(event) != CT_PR_EV_SIGNAL) { ct_event_free(event); continue; } ct_pr_event_get_pid(event, &pid); if (ct_pr_event_get_sender(event, &sender) == ENOENT) printf("process %ld killed by unknown process ", (long)pid); else printf("process %ld killed by process %ld ", (long)pid, (long)sender); ct_event_free(event); } ...
