tep_get_event - Man Page

#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);

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​.

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​.
