    Read a string until a newline is found, I don't think it's part of the standard - more of a compiler extension.

    [] is a list of characters to accept, ^ means the characters in the brackets won't be accepted.

    Basically,
    Code:
    %s = %[]
    Code:
    %1024s = %1024[]
    So if you only wanted to stop reading at a comma, fullstop or space it'd look like:
    Code:
    %[^,. ]
    Or if you only wanted to read commas, fullstops or spaces,
    Code:
    %[,. ]

    It is part of C99, at least.
