// Note that each manipulator function takes a single parameter called
// "__p". This name is defined in the SMANIP_make macro definition. Each
// function creates an object of type SMANIPint or SMANIPlong. It copies
// "__p" into the "__p" member of the returned object, and copies a
// function pointer into the "__f" member. Later, when the returned
// object is operated upon by << or >>, an indirect call is made via the
// stored function pointer, passing "__p" as a value. This called
// function is the one that actually changes the state of the stream.

// Handles "setfill" manipulator.
