/* FUNCTION <<atosfix16>>, <<atosfix32>>, <<atosfix64>>---string to signed fixed-point INDEX atosfix16 INDEX atosfix32 INDEX atosfix64 INDEX _atosfix16_r INDEX _atosfix32_r INDEX _atosfix64_r ANSI_SYNOPSIS #include <stdlib.h> __int16_t atosfix16(const char *<[s]>); __int32_t atosfix32(const char *<[s]>); __int64_t atosfix32(const char *<[s]>); __int16_t _atosfix16_r(struct __reent *, 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]>; const char *<[s]>; __int64_t _atosfix64_r(<reent>, <[s]>) 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. */ /* * Jeff Johnston - 02/13/2002 */ #ifdef __SPE__ #include <stdlib.h> #include <_ansi.h> __int16_t _DEFUN (_atosfix16_r, (reent, s), struct _reent *reent _AND _CONST char *s) { return _strtosfix16_r (reent, s, NULL); } #ifndef _REENT_ONLY __int16_t _DEFUN (atosfix16, (s), _CONST char *s) { return strtosfix16 (s, NULL); } #endif /* !_REENT_ONLY */ #endif /* __SPE__ */
