Simple readline algorithm for Networking

Are there any simple standardized way of reading a full line from a socket that mallocs the memory for you? If so, what are they? If not, is there a way to do it in approximately O(1) time (obviously not including the time for the memory allocation).

I agree with >>25 .  You can use C to make programs that do all sorts of cool shit, but you can't do cool shit inside the programming language itself unless you resort to code generation or other such non-C solutions.
