# stream_set_read_buffer

(PHP 5 >= 5.3.3)

stream_set_read_buffer — Set read file buffering on the given stream

### 説明

int stream_set_read_buffer ( resource `$stream` , int `$buffer` )

Sets the read buffer. It's the equivalent of stream_set_write_buffer(), but for read operations.

### パラメータ

`stream`

  The file pointer.

`buffer`

  The number of bytes to buffer. If `buffer` is 0 then read operations are unbuffered. This ensures that all reads with fread() are completed before other processes are allowed to write to that output stream.

### 返り値

Returns 0 on success, or EOF if the request cannot be honored.
