Created page with "This sets the source media of the location. =Syntax= <source lang="C"> void truxton_location_set_media_id( uint64_t location_handle, char const * id ); </source> =Parameters..."

New page

This sets the source media of the location.

=Syntax=
<source lang="C">
void truxton_location_set_media_id( uint64_t location_handle, char const * id );
</source>

=Parameters=
==<code>location_handle</code>==
This handle comes from calling <code>[[truxton_location_create]]()</code> or <code>[[truxton_child_file_create_location]]()</code>.

==<code>id</code>==
The string representation of a [https://en.wikipedia.org/wiki/Universally_unique_identifier GUID.]
It corresponds to the <code>[MediaID]</code> column of the <code><nowiki>[</nowiki>[[Location Table|Location]]<nowiki>]</nowiki></code> table.

=Remarks=
This identifier should be a value from the <code>[ID]</code> column of the<code>[Media]</code> table in the database.

=Sample=
<source lang="C" highlight="11">
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);
