This sets the longitude in part of the location.
Syntax
void truxton_location_set_latitude( uint64_t location_handle, double value );
Parameters
location_handle
This handle comes from calling truxton_location_create() or truxton_child_file_create_location().
value
The longitude in decimal degrees using the WGS84 ellipsoid.
It corresponds to the [Longitude] column of the [Location] table.
Sample
void new_location(uint64_t truxton, uint64_t file, double latitude, double longitude, double altitude, uint64_t when)
{
char guid_string[ 40 ];
uint64_t location = truxton_location_create(truxton);
truxton_file_get_id( file, guid_string, sizeof( guid_string ) );
truxton_location_set_file_id( location, guid_string );
truxton_file_get_media_id( file, guid_string, sizeof( guid_string ) );
truxton_location_set_media_id( location, guid_string );
truxton_location_set_latitude( location, latitude );
truxton_location_set_longitude( location, longitude );
truxton_location_set_altitude( location, altitude );
truxton_location_set_when( location, when );
truxton_location_set_type( location, LOCATION_TYPE_EXIF );
if ( truxton_location_save() == 0 )
{
printf( "Failed to create new location\n" );
}
else
{
truxton_location_get_id( location, guid_string, sizeof( guid_string ) );
printf( "Created new location as id %s\n", guid_string );
}
truxton_location_destroy(location);
}
