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.
