Summary

0000122: patch scanf.c: add a-flag conversion for vfscanf

Description

The patch adds glibc-like 'a' flag behaviour to vfscanf. The a-modifier is used in conjunction with s, S and [.

The wide character function vfwscanf is not affected by this patch, as it uses a completely different code path.

Notes
(0000063) mjn3 02-24-05 21:09	First, I'm not sure I want to support the 'a' flag at all since it leads to possible ambiguities with the ANSI/ISO C99 'a' conversion specifier. But even if I decided to, I would never apply the proposed patch as-is because it uses malloc/realloc without checking the return value.

(0000067) mtross 02-27-05 07:21	I've implemented the 'a' flag for portability reasons, and in the TODO list the 'a' flag is mentioned as a little thing that needs fixing. Therefore I thought it might be useful for you. Changed the patch to respect the return values of malloc and realloc.
