(PHP 4 >= 4.3.2, PHP 5)
streamWrapper::stream_seek — Seeks to specific location in a stream
$whence= SEEK_SET )
This method is called in response to fseek().
The read/write position of the stream should be updated according to the
The stream offset to seek to.
SEEK_SET- Set position equal to
SEEK_CUR- Set position to current location plus
SEEK_END- Set position to end-of-file plus
TRUE if the position was updated,
If not implemented,
FALSEis assumed as the return value.
Not all seeks operations on the stream will result in this function being called. PHP streams have read buffering enabled by default (see also stream_set_read_buffer()) and seeking may be done by merely moving the buffer pointer.
