EXTRA_LOOP_ARGS optional macro specifying extra arguments passed
to loop function.
STORE_REST optional, needed only when MAX_NEEDED_FROM > 4.
This macro stores the seen but unconverted input bytes
in the state.
FROM_ONEBYTE optional. 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
