LocalStream::stream_seek

public LocalStream::stream_seek($offset, $whence = SEEK_SET)

This method is called in response to fseek().

The read/write position of the stream should be updated according to the offset and whence.

Parameters

int $offset: The byte offset to seek to.

int $whence: Possible values:

• SEEK_SET: Set position equal to offset bytes.
• SEEK_CUR: Set position to current location plus offset.
• SEEK_END: Set position to end-of-file plus offset.

Defaults to SEEK_SET.

Return value

bool TRUE if the position was updated, FALSE otherwise.
