If defined, should be the name of a + specialized conversion function for a single byte + from the current character set to INTERNAL. This + function has prototype + wint_t + FROM_ONEBYTE (struct __gconv_step *, unsigned char); + and does a special conversion: + - The input is a single byte. + - The output is a single uint32_t. + - The state before the conversion is the initial state; + the state after the conversion is irrelevant. + - No transliteration. + - __invocation_counter = 0. + - __internal_use = 1. + - do_flush = 0. + + Modules can use mbstate_t to store conversion state as follows: + + * Bits 2..0 of '__count' contain the number of lookahead input bytes + stored in __value.__wchb. Always zero if the converter never + returns __GCONV_INCOMPLETE_INPUT. + + * Bits 31..3 of '__count' are module dependent shift state. + + * __value: When STORE_REST/UNPACK_BYTES aren't defined and when the + converter has returned __GCONV_INCOMPLETE_INPUT, this contains + at most 4 lookahead bytes. Converters with an mb_cur_max > 4 + (currently only UTF-8) must find a way to store their state + in __value.__wch and define STORE_REST/UNPACK_BYTES appropriately. + + When __value contains lookahead, __count must not be zero, because + the converter is not in the initial state then, and mbsinit() -- + defined as a (__count == 0) test -- must reflect this. + */ + +#include +#include +#include +#define __need_size_t +#define __need_NULL +#include + +#ifndef STATIC_GCONV +# include +#endif + +/* #include */ +#include + +#ifndef DL_CALL_FCT +# define DL_CALL_FCT(fct, args) fct args +#endif + +/* The direction objects. */ +#if DEFINE_INIT +# ifndef FROM_DIRECTION +# define FROM_DIRECTION_VAL NULL +# define TO_DIRECTION_VAL ((void *) ~((uintptr_t) 0)) +# define FROM_DIRECTION (step->__data == FROM_DIRECTION_VAL) +# endif +#else +# ifndef FROM_DIRECTION +# error "FROM_DIRECTION must be provided if non-default init is used" +# endif +#endif + +/* How many bytes are needed at most for the from-charset. */ +#ifndef MAX_NEEDED_FROM +# define MAX_NEEDED_FROM MIN_NEEDED_FROM +#endif + +/* Same for the to-charset. */ +#ifndef MAX_NEEDED_TO +# define MAX_NEEDED_TO MIN_NEEDED_TO +#endif + +/* Defaults for the per-direction min/max constants. */ +#ifndef FROM_LOOP_MIN_NEEDED_FROM +# define FROM_LOOP_MIN_NEEDED_FROM MIN_NEEDED_FROM +#endif +#ifndef FROM_LOOP_MAX_NEEDED_FROM +# define FROM_LOOP_MAX_NEEDED_FROM MAX_NEEDED_FROM +#endif +#ifndef FROM_LOOP_MIN_NEEDED_TO +# define FROM_LOOP_MIN_NEEDED_TO MIN_NEEDED_TO +#endif +#ifndef FROM_LOOP_MAX_NEEDED_TO +# define FROM_LOOP_MAX_NEEDED_TO MAX_NEEDED_TO +#endif +#ifndef TO_LOOP_MIN_NEEDED_FROM +# define TO_LOOP_MIN_NEEDED_FROM MIN_NEEDED_TO +#endif +#ifndef TO_LOOP_MAX_NEEDED_FROM +# define TO_LOOP_MAX_NEEDED_FROM MAX_NEEDED_TO +#endif +#ifndef TO_LOOP_MIN_NEEDED_TO +# define TO_LOOP_MIN_NEEDED_TO MIN_NEEDED_FROM +#endif +#ifndef TO_LOOP_MAX_NEEDED_TO +# define TO_LOOP_MAX_NEEDED_TO MAX_NEEDED_FROM +#endif + + +/* Define macros which can access unaligned buffers.
