# dio_truncate

(PHP 4 >= 4.2.0, PECL)

dio_truncate -- Truncates file descriptor fd to offset bytes

## Beskrivelse

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.

> Bemærk: Denne funktion er ikke implementeret på Windows platformen.

## Parameterliste

fd

  The file descriptor returned by dio_open().

offset

  The offset in bytes.

## Returneringsværdier

Returnerer `TRUE` ved succes, `FALSE` ved fejl.
