From 1217289737588e65b088b3535428b27c7287d699 Mon Sep 17 00:00:00 2001 From: Manuel Novoa III Date: Fri, 1 Aug 2003 20:08:59 +0000 Subject: Add a new *scanf implementation, includeing the *wscanf functions. Should be standards compliant and with several optional features, including support for hexadecimal float notation, locale awareness, glibc-like locale-specific digit grouping with the `'' flag, and positional arg support. I tested it pretty well (finding several bugs in glibc's scanf in the process), but it is brand new so be aware. The *wprintf functions now support floating point output. Also, a couple of bugs were squashed. Finally, %a/%A conversions are now implemented. Implement the glibc xlocale interface for thread-specific locale support. Also add the various *_l(args, locale_t loc_arg) funcs. NOTE!!! setlocale() is NOT threadsafe! NOTE!!! The strto{floating point} conversion functions are now locale aware. The also now support hexadecimal floating point notation. Add the wcsto{floating point} conversion functions. Fix a bug in mktime() related to dst. Note that unlike glibc's mktime, uClibc's version always normalizes the struct tm before attempting to determine the correct dst setting if tm_isdst == -1 on entry. Add a stub version of the libintl functions. (untested) Fixed a known memory leak in setlocale() related to the collation data. Add lots of new config options (which Erik agreed to sort out :-), including finally exposing some of the stripped down stdio configs. Be careful with those though, as they haven't been tested in a long time. (temporary) GOTCHAs... The ctype functions are currently incorrect for 8-bit locales. They will be fixed shortly. The ctype functions are now table-based, resulting in larger staticly linked binaries. I'll be adding an option to use the old approach in the stub locale configuration. --- libc/sysdeps/linux/common/bits/xopen_lim.h | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'libc/sysdeps/linux/common/bits/xopen_lim.h') diff --git a/libc/sysdeps/linux/common/bits/xopen_lim.h b/libc/sysdeps/linux/common/bits/xopen_lim.h index 90cb54123..c2363ab04 100644 --- a/libc/sysdeps/linux/common/bits/xopen_lim.h +++ b/libc/sysdeps/linux/common/bits/xopen_lim.h @@ -68,7 +68,13 @@ /* Maximum value of `digit' in calls to the `printf' and `scanf' functions.
