        __uint32_t atoufix32(<[s]>)

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.
