  <para>
   Sets the read buffer. It's the equivalent of <function>stream_set_write_buffer</function>,
   but for read operations.

     <para>
      The number of bytes to buffer. If <parameter>size</parameter>
      is 0 then read operations are unbuffered.  This ensures that all reads
      with <function>fread</function> are completed before other processes are
      allowed to read from that input stream.
