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);
                   }
           }
