DESCRIPTION
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_sig‐
nal(), 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 dis‐
play the signalled pid and signalling pid for each CT_PR_EV_SIGNAL
event encountered.
