From: Andres Salomon Date: Mon, 17 Dec 2007 06:34:58 +0000 (-0500) Subject: kconfig: use getopt() in conf.c for handling command line arguments X-Git-Tag: v2.6.25-rc1~1164^2~63 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2f4b489b77c68b9cba1bd9dec5a1bbf0ab3c47f8;p=linux-2.6 kconfig: use getopt() in conf.c for handling command line arguments Switch from doing our own parsing of command line arguments to using getopt(3) to do it. Aside from simplifying things, this allows us to specify multiple arguments; the old code could only accept two arguments (input_mode and kconfig name). Note some subtle changes: - The argument '-?' is no longer supported. - '-h' is not treated as an error, so output goes to stdout, and we exit with '0'. - There is no compatibility checking amongst arguments; the last option will simply override earlier options. For example, 'conf -n -y foo' is perfectly valid now (input_mode will be set_yes). Previously, that would have been an error ("can't find file -y").
