Update.
* intl/gettextP.h (struct loaded_domain): Add conv element. * intl/dcgettext.c (find_msg): Rename to _nl_find_msg and make public. Instead of returning found message directly convert it using iconv if a conversion was found when opening the file. * intl/loadinfo.h: Protect against multiple inclusion. Declare _nl_find_msg. * intl/loadmsgcat.c (_nl_load_domain): Try to determine charset used in the message file and if necessary find approrpiate conversion to match currently selected charset.

@ -18,18 +18,57 @@ comments. You could also use the `-D' option to GCC, but it's better
|
||||
if you make the source files indicate their own meaning in a
|
||||
self-contained way.
|
||||
|
||||
This system exists to allow the library to conform to multiple
|
||||
standards. Although the different standards are often described as
|
||||
supersets of each other, they are usually incompatible because larger
|
||||
standards require functions with names that smaller ones reserve to the
|
||||
user program. This is not mere pedantry -- it has been a problem in
|
||||
practice. For instance, some non-GNU programs define functions named
|
||||
`getline' that have nothing to do with this library's `getline'. They
|
||||
would not be compilable if all features were enabled indescriminantly.
|
||||
|
||||
This should not be used to verify that a program conforms to a
|
||||
limited standard. It is insufficent for this purpose, as it will not
|
||||
protect you from including header files outside the standard, or
|
||||
relying on semantics undefined within the standard.
|
||||
|
||||
- Macro: _POSIX_SOURCE
|
||||
If you define this macro, then the functionality from the POSIX.1
|
||||
standard (IEEE Standard 1003.1) is available, as well as all of the
|
||||
ISO C facilities.
|
||||
|
||||
The state of `_POSIX_SOURCE' is irrelevant if you define the macro
|
||||
`_POSIX_C_SOURCE' to a positive integer.
|
||||
|
||||
- Macro: _POSIX_C_SOURCE
|
||||
If you define this macro with a value of `1', then the
|
||||
functionality from the POSIX.1 standard (IEEE Standard 1003.1) is
|
||||
made available. If you define this macro with a value of `2',
|
||||
then both the functionality from the POSIX.1 standard and the
|
||||
functionality from the POSIX.2 standard (IEEE Standard 1003.2) are
|
||||
made available. This is in addition to the ISO C facilities.
|
||||
Define this macro to a positive integer to control which POSIX
|
||||
functionality is made available. The greater the value of this
|
||||
macro, the more functionality is made available.
|
||||

If you define this macro to a value greater than or equal to `1',

then the functionality from the 1990 edition of the POSIX.1

standard (IEEE Standard 1003.1-1990) is made available.

If you define this macro to a value greater than or equal to `2',
|
||||
then the functionality from the 1992 edition of the POSIX.2
|

standard (IEEE Standard 1003.2-1992) is made available.
|

If you define this macro to a value greater than or equal to
|
||||
`199309L', then the functionality from the 1993 edition of the
|
||||
POSIX.1b standard (IEEE Standard 1003.1b-1993) is made available.
|
||||
|
||||
Greater values for `_POSIX_C_SOURCE' will enable future extensions.
|
||||
The POSIX standards process will define these values as necessary,
|
||||
and the GNU C Library should support them some time after they
|
||||
become standardized. The 1996 edition of POSIX.1 (ISO/IEC 9945-1:
|
||||
1996) states that if you define `_POSIX_C_SOURCE' to a value
|
||||
greater than or equal to `199506L', then the functionality from
|
||||
the 1996 edition is made available.
|

the value `199506L' selects all the values specified by the POSIX
