Truxton location get type

This retrieves location type. This corresponds to the [LocationTypeID] column of the [Location] table and should contain a value found in the [ID] column of the [LocationType] table. It can also be one of the defined constants.

Syntax

uint64_t truxton_location_get_type( uint64_t location_handle );

Parameters

location_handle

This handle comes from calling truxton_location_create() or truxton_child_file_create_location()

Return value

The location's type.

Sample

void dump_location( uint64_t location_handle )
{
   double value = 0;
   uint64_t ticks = 0;
   char guid_string[ 40 ];
   char label[ 256 ];

   truxton_location_get_label( location_handle, label, sizeof( label ) );
   printf( "%s\n", label );

   truxton_location_get_file_id( location_handle, guid_string, sizeof( guid_string ) );
   printf( "File ID: %s\n", guid_string );

   truxton_location_get_media_id( location_handle, guid_string, sizeof( guid_string ) );
   printf( "Media ID: %s\n", guid_string );

   value = truxton_location_get_latitude( location_handle );
   printf( "Latitude: %lf\n", value );

   value = truxton_location_get_longitude( location_handle );
   printf( "Longitude: %lf\n", value );

   value = truxton_location_get_altitude( location_handle );
   printf( "Altitude: %lf meters\n", value );

   ticks = truxton_location_get_type( location_handle );
   printf( "Type: %" PRIu64 "\n", ticks );

   ticks = truxton_location_get_when( location_handle );
   printf( "Ticks: %" PRIu64 "\n", ticks );
}

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.
