412 You have to check the return value - the length of the buffer actually read -
413 or use the safe IO functions in the high-level IO utility module.
415 <li>The length of the return buffer is limited by the (compile time)
416 nixio buffersize which is
<em>nixio.const.buffersize
</em> (
8192 by default).
417 Any read request greater than that will be safely truncated to this value.

443 buffer: Buffer holding the data to be written.
447 offset: Offset to start reading the buffer from. (optional)
451 length: Length of chunk to read from the buffer. (optional)
462 <li>This function calls SSL_write().
464 <li><strong>Warning:

465 in the buffer is written at once.
466 You have to check the return value - the number of bytes actually written -

0.
