When these bits are on you * are restoring an existing Solaris behavior and no longer * in strict C99/SUSv3 conformance mode. * * The lower 16 bits (default_on) are C99/SUSv3 behaviors * which are strictly conforming behaviors as far as the * C99/SUSv3 standards are concerned. When these bits are on * you are in C99/SUSv3 conforming mode. When these bits are off * you have turned off C99/SUSv3 conforming mode and are using * previous Solaris behavior. * * _C99SUSv3_mode_ON and _C99SUSv3_mode_OFF are two meta-definitions * which are the most likely modes to run Solaris in. * However, this frame work allows for other possible behaviors. * * The default mode of libc is _C99SUSv3_mode_OFF. * A C99/SUSv3 conforming application should be compiled * with the XPG6 standards conforming C compiler utility (c99) which * adds an object file that contains an alternate definition * for __xpg6 (_C99SUSv3_mode_ON) thus enabling C99/SUSv3 standards * conforming mode. */ #define _C99SUSv3_default_off_reserved15 0x80000000 #define _C99SUSv3_default_off_reserved14 0x40000000 #define _C99SUSv3_default_off_reserved13 0x20000000 #define _C99SUSv3_default_off_reserved12 0x10000000 #define _C99SUSv3_default_off_reserved11 0x08000000 #define _C99SUSv3_default_off_reserved10 0x04000000 #define _C99SUSv3_default_off_reserved09 0x02000000 #define _C99SUSv3_default_off_reserved08 0x01000000 #define _C99SUSv3_default_off_reserved07 0x00800000 #define _C99SUSv3_default_off_reserved06 0x00400000 #define _C99SUSv3_default_off_reserved05 0x00200000 #define _C99SUSv3_default_off_reserved04 0x00100000 #define _C99SUSv3_default_off_reserved03 0x00080000 #define _C99SUSv3_default_off_reserved02 0x00040000 #define _C99SUSv3_default_off_reserved01 0x00020000 /* * If set then %f & %F print Inf/NaN; * else print inf/nan & INF/NAN, respectively. */ #define _C99SUSv3_mixed_case_Inf_and_NaN 0x00010000 #define _C99SUSv3_default_on_reserved15 0x00008000 #define _C99SUSv3_default_on_reserved14 0x00004000 #define _C99SUSv3_default_on_reserved13 0x00002000 #define _C99SUSv3_default_on_reserved12 0x00001000 #define _C99SUSv3_default_on_reserved11 0x00000800 /* * If set, math library entry points present in SUSv2 deal with exceptional * cases as per SUSv3 spec where math_errhandling is set to MATH_ERREXCEPT; * otherwise they behave as per SUSv2 spec. */ #define _C99SUSv3_math_errexcept 0x00000400 /* * If set, when filename is a null pointer, freopen(NULL, mode, ...) will * attempt to change the mode of the stream to that specified by mode, as if * the name of the file currently associated with the stream had been used; * otherwise freopen(NULL, ...) will fail. */ #define _C99SUSv3_freopen_NULL_filename 0x00000200 /* * If set, * - strfmon() uses int_* members for %i * - strfmon() handles the case n_sep_by_space == 2 as SUSv3 expects, * which is different from it does in non SUSv3 mode. */ #define _C99SUSv3_strfmon 0x00000100 /* * If set, pow(+/-1,+/-Inf) & pow(1,NaN) return 1; otherwise NaN is returned. * Analogous comment applies to powf and powl. */ #define _C99SUSv3_pow_treats_Inf_as_an_even_int 0x00000080 /* * If set, logb(subnormal) returns (double) ilogb(subnormal); otherwise * logb(subnormal) returns logb(DBL_MIN).
