dio_truncate — Truncates file descriptor fd to offset bytes
Description
bool dio_truncate
( resource $fd
, int $offset
)
dio_truncate() truncates a file to at most offset bytes in size.
If the file previously was larger than this size, the extra data is lost. If the file previously was shorter, it is unspecified whether the file is left unchanged or is extended. In the latter case the extended part reads as zero bytes.
Note: Deze functie is niet geïmplementeerd in de Windows versie van PHP.
