| 18 | SYNOPSIS |
|---|
| 19 | #include <stdlib.h> |
|---|
| 20 | __int16_t atosfix16(const char *<[s]>); |
|---|
| 21 | __int32_t atosfix32(const char *<[s]>); |
|---|
| 22 | __int64_t atosfix32(const char *<[s]>); |

| 24 | __int16_t _atosfix16_r(struct __reent *, const char *<[s]>); |
|---|
| 25 | __int32_t _atosfix32_r(struct __reent *, const char *<[s]>); |
|---|
| 26 | __int64_t _atosfix32_r(struct __reent *, const char *<[s]>); |
|---|
| 27 | |
|---|
| 28 | DESCRIPTION |
|---|
| 29 | <<atosfix16>> converts the initial portion of a string to a sign |
|---|
| 30 | + 15-bit fraction fixed point value. |
|---|
| 31 | <<atosfix32>> converts the initial portion of a string to a sign |
|---|
| 32 | + 31-bit fraction fixed point value. |
|---|
| 33 | <<atosfix64>> converts the initial portion of a string to a sign |
|---|
| 34 | + 63-bit fraction fixed point value. |
|---|
| 35 | <<atosfix16(s)>> is implemented as <<strtosfix16(s, NULL).>> |
|---|
| 36 | <<atosfix32(s)>> is implemented as <<strtosfix32(s, NULL).>> |
|---|
| 37 | <<atosfix64(s)>> is implemented as <<strtosfix64(s, NULL).>> |
|---|
| 38 | |
|---|
| 39 | The alternate functions <<_atosfix16_r>>, <<_atosfix32_r>>, |
|---|
| 40 | and <<_atosfix64_r>> are reentrant versions. |
|---|
| 41 | The extra argument <[reent]> is a pointer to a reentrancy structure. |
|---|
| 42 | |
|---|
| 43 | RETURNS |
|---|
| 44 | The functions return the converted value, if any. If no conversion was |
|---|
| 45 | made, <<0>> is returned. If saturation occurs, <<ERANGE>> is stored |
|---|
| 46 | in errno. |
|---|
| 47 | |
|---|
| 48 | PORTABILITY |
|---|
| 49 | <<atosfix16>>, <<atosfix32>>, and <<atosfix64>> are non-standard. |
|---|
| 50 | |
|---|
| 51 | No supporting OS subroutines are directly required. The |
|---|
| 52 | OS subroutines required by <<strtod>> are used. |
