<p>Recently, I found two functions <code>setbuf()</code> and <code>setvbuf()</code> can be used to set stream buffer. What's the meaning of the letter <code>v</code> in the name <code>setvbuf</code>? Is it <code>various</code>, <code>version</code> or something else?</p>

What's the meaning of the letter ‘v’ in setvbuf()?

I didn't found any explanation of 'v' anywhere but I guess it may be 'variable' since it allows to specify the size and mode of the buffer.
