This file describes the implementation status and some notes; information is
|
|
taken from the C99 standard (ISO/IEC 9899:1999), section 7 ("Library").
|
|
|
|
Notes for implementers:
|
|
|
|
7.1.2§6:
|
|
Use (extern) in all function prototypes
|
|
7.1.3§1:
|
|
Only expose standard identifiers; anything else might be defined as a macro.
|
|
Make sure every argument name, internal function name, etc. starts with
|
|
either "__" or "_X" (where X is any uppercase letter)
|
|
7.1.4§1:
|
|
Always give a function even if there is a macro definition, so that the
|
|
address of the function can be taken; don't rely on the macro being defined,
|
|
as the user can remove it except in some special cases
|
|
|
|
In this file, every definition is classified in one of several implementation
|
|
statuses. There are 5 stages that every definition should go through.

What if we wanted to support more locales?
|
|
-> Need to a mechanism to supply the raw information, similar to the text
|
|
files in /usr/share/i18n/locales
|
|
-> Implement setlocale() and localeconv() properly (not hard)
|
|
-> Probably support nl_langinfo(), which is much better than localeconv()
|
|
-> Fix the "TODO: locale: ..." messages wherever assumptions on the locale
|
|
are made in the code
