# tep\_get\_event(3)

Access events.

## NAME

tep\_get\_event, tep\_get\_first\_event, tep\_get\_events\_count - Access events.

## SYNOPSIS

```
#include <event-parse.h>
struct tep_event *tep_get_event(struct tep_handle *tep, int index);
struct tep_event *tep_get_first_event(struct tep_handle *tep);
int tep_get_events_count(struct tep_handle *tep);
```

## DESCRIPTION

The **tep\_get\_event()** function returns a pointer to event at the given *index*. The *tep* argument is trace event parser context, the *index* is the index of the requested event.

The **tep\_get\_first\_event()** function returns a pointer to the first event. As events are stored in an array, this function returns the pointer to the beginning of the array. The *tep* argument is trace event parser context.

The **tep\_get\_events\_count()** function returns the number of the events in the array. The *tep* argument is trace event parser context.

## RETURN VALUE

The **tep\_get\_event()** returns a pointer to the event located at *index*. NULL is returned in case of error, in case there are no events or *index* is out of range.

The **tep\_get\_first\_event()** returns a pointer to the first event. NULL is returned in case of error, or in case there are no events.

The **tep\_get\_events\_count()** returns the number of the events. 0 is returned in case of error, or in case there are no events.

## EXAMPLE

```
#include <event-parse.h>
...
struct tep_handle *tep = tep_alloc();
...
int i,count = tep_get_events_count(tep);
struct tep_event *event, *events = tep_get_first_event(tep);
if (events == NULL) {
        /* There are no events */
} else {
        for (i = 0; i < count; i++) {
                event = (events+i);
                /* process events[i] */
        }
        /* Get the last event */
        event = tep_get_event(tep, count-1);
}
```
