# streamWrapper::stream_seek

(PHP 4 >= 4.3.2, PHP 5)

streamWrapper::stream_seek — Seeks to specific location in a stream

### 설명

public bool streamWrapper::stream_seek ( int `$offset` , int `$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` .

### 인수

`offset`

  The stream offset to seek to.

`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` .

### 반환값

Return `TRUE` if the position was updated, `FALSE` otherwise.

### 주의

> Note: If not implemented, `FALSE` is assumed as the return value.

> Note: Upon success, streamWrapper::stream_tell is called directly after calling streamWrapper::stream_seek. If streamWrapper::stream_tell fails, the return value to the caller function will be set to `FALSE`

### 참고

- fseek() - Seeks on a file pointer
