data input in binary format

Hi all,
I would like to know if it is possible for scanf() function
in C to read input from a keyboard in binary form or some
code for conversion has to be written for conversion to
binary format first.
If possible to read binary input directly by scanf()
what is the conversion specification used?

Thanks in advance,

Aamir
