/* This file can be included to provide definitions of several things
|
|
many modules have in common. It can be customized using the following
|
|
macros:
|
|
|
|
DEFINE_INIT define the default initializer. This requires the
|
|
following symbol to be defined.
|
|
|
|
CHARSET_NAME string with official name of the coded character
|
|
set (in all-caps)
|
|
|
|
DEFINE_FINI define the default destructor function.
|
|
|
|
MIN_NEEDED_FROM minimal number of bytes needed for the from-charset.
|
|
MIN_NEEDED_TO likewise for the to-charset.
|
|
|
|
MAX_NEEDED_FROM maximal number of bytes needed for the from-charset.
|
|
This macro is optional, it defaults to MIN_NEEDED_FROM.
|
|
MAX_NEEDED_TO likewise for the to-charset.
|
|
|
|
FROM_LOOP_MIN_NEEDED_FROM
|
|
FROM_LOOP_MAX_NEEDED_FROM
|
|
minimal/maximal number of bytes needed on input
|
|
of one round through the FROM_LOOP. Defaults
|
|
to MIN_NEEDED_FROM and MAX_NEEDED_FROM, respectively.
|
|
FROM_LOOP_MIN_NEEDED_TO
|
|
FROM_LOOP_MAX_NEEDED_TO
|
|
minimal/maximal number of bytes needed on output
|
|
of one round through the FROM_LOOP. Defaults
|
|
to MIN_NEEDED_TO and MAX_NEEDED_TO, respectively.
|
|
TO_LOOP_MIN_NEEDED_FROM
|
|
TO_LOOP_MAX_NEEDED_FROM
|
|
minimal/maximal number of bytes needed on input
|
|
of one round through the TO_LOOP. Defaults
|
|
to MIN_NEEDED_TO and MAX_NEEDED_TO, respectively.
|
|
TO_LOOP_MIN_NEEDED_TO
|
|
TO_LOOP_MAX_NEEDED_TO
|
|
minimal/maximal number of bytes needed on output
|
|
of one round through the TO_LOOP. Defaults
|
|
to MIN_NEEDED_FROM and MAX_NEEDED_FROM, respectively.
|
|
|
|
DEFINE_DIRECTION_OBJECTS
|
|
two objects will be defined to be used when the
|
|
`gconv' function must only distinguish two
|
|
directions. This is implied by DEFINE_INIT.
|
|
If this macro is not defined the following
|
|
macro must be available.
|
|
|
|
FROM_DIRECTION this macro is supposed to return a value != 0
|
|
if we convert from the current character set,
|
|
otherwise it return 0.
|
|
|
|
EMIT_SHIFT_TO_INIT this symbol is optional. If it is defined it
|
|
defines some code which writes out a sequence
|
|
of bytes which bring the current state into
|
|
the initial state.
|
|
|
|
FROM_LOOP name of the function implementing the conversion
|
|
from the current character set.
|
|
TO_LOOP likewise for the other direction
|
|
|
|
ONE_DIRECTION optional. If defined to 1, only one conversion
|
|
direction is defined instead of two. In this
|
|
case, FROM_DIRECTION should be defined to 1, and
|
|
FROM_LOOP and TO_LOOP should have the same value.
|
|
|
|
SAVE_RESET_STATE in case of an error we must reset the state for
|
|
the rerun so this macro must be defined for
|
|
stateful encodings. It takes an argument which
|
|
is nonzero when saving.
|
|
|
|
RESET_INPUT_BUFFER If the input character sets allow this the macro
|
|
can be defined to reset the input buffer pointers
|
|
to cover only those characters up to the error.
|
|
|
|
FUNCTION_NAME if not set the conversion function is named `gconv'.
|
|
|
|
PREPARE_LOOP optional code preparing the conversion loop. Can
|
|
contain variable definitions.
|
|
END_LOOP also optional, may be used to store information
|
|
|
|
EXTRA_LOOP_ARGS optional macro specifying extra arguments passed
|
|
to loop function.
|
|
|
|
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.
