TRAD_SYNOPSIS
	#include <stdlib.h>

DESCRIPTION
	<<atosfix16>> converts the initial portion of a string to a sign
	+ 15-bit fraction fixed point value.
	<<atosfix32>> converts the initial portion of a string to a sign
	+ 31-bit fraction fixed point value.
	<<atosfix64>> converts the initial portion of a string to a sign
	+ 63-bit fraction fixed point value.
	<<atosfix16(s)>> is implemented as <<strtosfix16(s, NULL).>>
	<<atosfix32(s)>> is implemented as <<strtosfix32(s, NULL).>>
	<<atosfix64(s)>> is implemented as <<strtosfix64(s, NULL).>>
 
	The alternate functions <<_atosfix16_r>>, <<_atosfix32_r>>,
	and <<_atosfix64_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
	<<atosfix16>>, <<atosfix32>>, and <<atosfix64>> are non-standard.
 
	No supporting OS subroutines are directly required.  The
	OS subroutines required by <<strtod>> are used.
