Some hint requests for read_line variations

[emmba]

The premise for my assignment is to write variations of the read_line
functions. The variations are:
a) skips leading whitespace before storing input
b) stops reading at first whitespace character
c) leaves behind characters that it does not have room to store

Could anyone give me a couple hints? I'm not really sure where to
start. Thanks!
