This retrieves the GUID of the parent file of this file.
It corresponds to the [ParentID] column of the [File] table.
The file identifier is not random.
Syntax
void truxton_file_get_parent_id( uint64_t file_handle, char * destination_string, size_t max_size );
Parameters
file_handle
The handle created by the truxton_file_open_id or truxton_file_open_md5 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 file = truxton_file_open_md5( truxton, "9ec8fb6095c35eff2b236863b7caaf10" );
if ( file != 0 )
{
return;
}
char guid_string[ 40 ];
truxton_file_get_parent_id( file, guid_string, sizeof(guid_string) );
truxton_file_free( file );
printf( "Parent file ID is %s\n", guid_string );
}
