TRAD_SYNOPSIS

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.
