This retrieves the GUID of the latest root file in the media.
This corresponds to the [ID] column of the [File] table.
Syntax
void truxton_media_get_root_file_id( uint64_t media_handle, char * destination_string, size_t max_size );
Parameters
media_handle
The handle created by the truxton_media_open_id or truxton_media_create call.
destination_string
The string to be written to.
max_size
The maximum number of characters that can be written to destination_string.
Sample
void print_id( uint64_t truxton )
{
uint64_t media = truxton_media_open_id( truxton, "1506fd04-3b7f-a872-ba0d-ec43efbdcf9e" );
if ( media != 0 )
{
return;
}
char guid_string[ 40 ];
truxton_media_get_root_file_id( media, guid_string, sizeof(guid_string) );
truxton_media_free( media );
printf( "Media Root ID is %s\n", guid_string );
}
