NAME

       tep_find_event, tep_find_event_by_name, tep_find_event_by_record - Find events by given
       key.

SYNOPSIS

       #include <event-parse.h>

       struct tep_event *tep_find_event(struct tep_handle *tep, int id);
       struct tep_event *tep_find_event_by_name(struct tep_handle *tep, const char *sys, const char *name);
       struct tep_event *tep_find_event_by_record(struct tep_handle *tep, struct tep_record *record);

DESCRIPTION

       This set of functions can be used to search for an event, based on a given criteria. All
       functions require a pointer to a tep, trace event parser context.

       The tep_find_event() function searches for an event by given event id. The event ID is
       assigned dynamically and can be viewed in event’s format file, "ID" field.

       The tep_find_event_by_name() function searches for an event by given event name, under the
       system sys. If the sys is NULL (not specified), the first event with name is returned.

       The tep_find_event_by_record()* function searches for an event from a given record.

RETURN VALUE

       All these functions return a pointer to the found event, or NULL if there is no such
       event.

EXAMPLE

           #include <event-parse.h>
           ...
           struct tep_handle *tep = tep_alloc();
           ...
           struct tep_event *event;

           event = tep_find_event(tep, 1857);
           if (event == NULL) {
                   /* There is no event with ID 1857 */
           }

           event = tep_find_event_by_name(tep, "kvm", "kvm_exit");
           if (event == NULL) {
                   /* There is no kvm_exit event, from kvm system */
           }

           void event_from_record(struct tep_record *record)
           {
            struct tep_event *event = tep_find_event_by_record(tep, record);
                   if (event == NULL) {
                           /* There is no event from given record */
                   }
           }
           ...
