DESCRIPTION
	<<atoufix16>> converts the initial portion of a string to a
	16-bit fraction unsigned fixed point value.
	<<atoufix32>> converts the initial portion of a string to a
	32-bit fraction unsigned fixed point value.
	<<atoufix64>> converts the initial portion of a string to a
	64-bit fraction unsigned fixed point value.
	<<atoufix16(s)>> is implemented as <<strtoufix16(s, NULL).>>
	<<atoufix32(s)>> is implemented as <<strtoufix32(s, NULL).>>
	<<atoufix64(s)>> is implemented as <<strtoufix64(s, NULL).>>
 
	The alternate functions <<_atoufix16_r>>, <<_atoufix32_r>>,
	and <<_atoufix64_r>> are reentrant versions.
	The extra argument <[reent]> is a pointer to a reentrancy structure.
 
RETURNS
	The functions return the converted value, if any. If no conversion was
	made, <<0>> is returned.  If saturation occurs, <<ERANGE>> is stored
	in errno.
 
PORTABILITY
	<<atoufix16>>, <<atoufix32>>, and <<atoufix64>> are non-standard.
 
	No supporting OS subroutines are directly required.  The
	OS subroutines required by <<strtod>> are used.
