dio_truncate
(PHP 4 >= 4.2.0)
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
TRUE on success or FALSE on failure..
