Truxton event type get id

This retrieves the event type identifier. This corresponds to the [ID] column of the [EventType] table. It will be stored in the [EventTypeID] column of the [Event] table in the database.

Syntax

uint64_t truxton_event_type_get_id( uint64_t event_type_handle );

Parameters

event_type_handle

This handle comes from calling truxton_event_type_create().

Return value

The value of the type id.

Sample

void create_event_type( void )
{
   uint64_t truxton = truxton_create();

   uint64_t event_type = truxton_event_type_create( truxton );

   truxton_event_type_set_id( event_type, 21212 );
   truxton_event_type_set_name( event_type, "FBI Action" );

   if ( truxton_event_type_save( event_type ) == 0 )
   {
      printf("Cannot save event type to the database.\n");
   }
   else
   {
      char type_name[ 128 ];

      uint64_t new_id = truxton_event_type_get_id( event_type );

      truxton_event_type_get_name( event_type, type_name, sizeof( type_name ) ); 
      printf( "Created %s event type as id %" PRIu64 "\n", type_name, new_id );
   }

   truxton_event_type_destroy( event_type );
   truxton_destroy( truxton );
}

The PRIu64 in the sample code above is a standard way of formatting a 64-bit unsigned integer in C. Over the years, different compilers on different operating systems used different format specifiers for things, these PRI macros, along with some tricky string concatenation the compilers perform for you, allow you to maintain a single code base without a bunch of macro magic.
