Truxton event type create
Jump to navigation
Jump to search
This creates an event type object. You can use this to extend Truxton with new types of events.
Syntax
uint64_t truxton_event_type_create( uint64_t truxton_handle );
Parameters
truxton_handle
The Truxton instance this event type will belong.
This handle comes from calling truxton_create().
Return value
A handle to an event type object.
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.
