read-fixnum PORTprocedure
read-flonum PORTprocedure
read-complex PORTprocedure
read-one-char PORTprocedure

These procedures read one object of a specific type from an input-port. There are no runtime checks in the Scheme way; the procedures will just call error if anything goes wront (EOF, lexical error etc).
