ANSI_SYNOPSIS
#include <stdlib.h>
__int16_t atosfix16(const char *<[s]>);
__int32_t atosfix32(const char *<[s]>);
__int64_t atosfix32(const char *<[s]>);

__int32_t _atosfix32_r(struct __reent *, const char *<[s]>);
__int64_t _atosfix32_r(struct __reent *, const char *<[s]>);
TRAD_SYNOPSIS
#include <stdlib.h>
__int16_t atosfix16(<[s]>)
const char *<[s]>;
__int32_t atosfix32(<[s]>)
const char *<[s]>;
__int64_t atosfix64(<[s]>)
const char *<[s]>;
__int16_t _atosfix16_r(<reent>, <[s]>)
struct _reent *<[reent]>;
const char *<[s]>;
__int32_t _atosfix32_r(<reent>, <[s]>)
struct _reent *<[reent]>;

struct _reent *<[reent]>;
const char *<[s]>;
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.
