scanf on non-STDIN input

Is it possible to run scanf on input that it is not STDIN? What I mean is if I have a string="hello 1 2 3", can I run scanf on it to extract the str开发者_StackOverflow中文版ing and three integers?

Is there another function that can do this?

sscanf on a string (info here)

fscanf on a file (info here)

similarly sprintf and fprintf to write to a string/file.

If you have a string, sscanf would be more appropriate. The title of your question implies reading from a different stream, for which there are other similar functions (see fscanf).
