# dio_truncate

(PHP 4 CVS only)

dio_truncate -- Truncates file descriptor fd to offset bytes

## Description

``bool dio_truncate` (resource fd, int offset)`

Function dio_truncate() causes the file referenced by `fd` to be truncated 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. Returns 0 on success, otherwise -1
