Update.
1998-04-07 08:51 Ulrich Drepper <drepper@cygnus.com> * iconv/gconv.c: Take care for NULL arguments. * iconv/gconv_dl.c: Make find_func function global. * iconv/gconv_int.h: Add prototype for __gconv_find_func. Add prototypes for ASCII conversion functions. * iconv/gconv_simple.c: Add ASCII conversion functions. * locale/C-ctype.c: Correct charset name. * wcsmbs/Makefile (distribute): Add wcsmbsload.h. (routines): Remove wmemrtowcs and wmemrtombs, add wcsnlen and wcsmbsload. * wcsmbs/btowc.c: Rewrite to use iconv functionality. * wcsmbs/mbrtowc.c: Likewise. * wcsmbs/mbsnrtowcs.c: Likewise. * wcsmbs/mbsrtowcs.c: Likewise. * wcsmbs/wcrtomb.c: Likewise. * wcsmbs/wcsnrtombs.c: Likewise. * wcsmbs/wcsrtombs.c: Likewise. * wcsmbs/wctob.c: Likewise. * wcsmbs/wchar.h: Add prototype for __wcslen, wcsnlen. Remove prototypes for wmemr*. * wcsmbs/wcslen.c: Rename to __wcslen and make wcslen weak alias. * wcsmbs/wcsnlen.c: New file. * wcsmbs/wcsmbsload.c: New file. * wcsmbs/wcsmbsload.h: New file. * manual/filesys.texi: Mention risks of tmpnam and mktemp. * manual/install.texi: Describe some more critical points. * string/string.h: Add prototype for __strnlen. * string/strnlen.c: Rename to __strnlen and make strnlen weak alias. * sysdeps/posix/mktemp.c: Rewrite to allow many more files and much less predictable names. * sysdeps/posix/mkstemp.c: Likewise. 1998-04-05 Andreas Jaeger <aj@arthur.rhein-neckar.de> * manual/libc.texinfo (Top): Change "file namespace" to "local namespace". * manual/socket.texi: Change file namespace to local namespace. (Out-of-Band Data): Remove unneeded variable link. (Host Address Functions): Use uint32_t consequently and add a number of clarifications for IPv4/IPv6, classless addresses. (Internet Namespace): Added some paragraphs about IPv6. Based on suggestions by Francesco Potorti` <F.Potorti@cnuce.cnr.it>. 1998-04-05 Philip Blundell <Philip.Blundell@pobox.com> Update for draft-ietf-ipngwg-bsd-api-new-01.txt: * resolv/netdb.h (getnameinfo): Use `socklen_t' not `size_t'.
