c - Reading multiple lines of input with scanf()

Question

Relevant code snippet:

char input [1024];

printf("Enter text. Press enter on blank line to exit.
");
scanf("%[^
]", input);

That will read the whole line up until the user hits [enter], preventing the user from entering a second line (if they wish).

To exit, they hit [enter] and then [enter] again. So I tried all sorts of while loops, for loops, and if statements around the scanf() involving the new line escape sequence but nothing seems to work.

Any ideas?

Try this:

while (1 == scanf("%[^
]%*c", input)) { /* process input */ }
