NAME
tep_event_common_fields, tep_event_fields - Get a list of fields for an event.
SYNOPSIS
#include <event-parse.h>
struct
tep_format_field **
tep_event_common_fields
(struct
tep_event *
event
);
struct tep_format_field **
tep_event_fields
(struct
tep_event *
event
);
DESCRIPTION
The tep_event_common_fields() function returns an array of pointers to common fields for the event . The array is allocated in the function and must be freed by free(). The last element of the array is NULL.
The tep_event_fields() function returns an array of pointers to event specific fields for the event . The array is allocated in the function and must be freed by free(). The last element of the array is NULL.
RETURN VALUE
Both tep_event_common_fields() and tep_event_fields() functions return an array of pointers to tep_format_field structures in case of success, or NULL in case of an error.
EXAMPLE
#include
<event-parse.h>
...
struct tep_handle *tep = tep_alloc();
...
int i;
struct tep_format_field **fields;
struct tep_event *event = tep_find_event_by_name(tep,
"kvm", "kvm_exit");
if (event != NULL) {
fields = tep_event_common_fields(event);
if (fields != NULL) {
i = 0;
while (fields[i]) {
/*
walk through the list of the common fields
of the kvm_exit event
*/
i++;
}
free(fields);
}
fields = tep_event_fields(event);
if (fields != NULL) {
i = 0;
while (fields[i]) {
/*
walk through the list of the event specific
fields of the kvm_exit event
*/
i++;
}
free(fields);
}
}
