| 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. |
