From f6e9cebd79044b1ca54648ecdadd13db8c4673dc Mon Sep 17 00:00:00 2001 From: sandman Date: Mon, 30 Sep 2002 00:29:12 +0000 Subject: - added an option to quit to console - launcher is now started via a login shell - font is "hardcoded" to helvetica - screen saver is "hardcoded" to 30/20/60 secs (this should make opie-login usable, regardless of any (miss)-configuration of the normal OPIE appearance) --- (limited to 'core/opie-login/main.cpp') diff --git a/core/opie-login/main.cpp b/core/opie-login/main.cpp index 44d6f8d..718009a 100644 --- a/core/opie-login/main.cpp +++ b/core/opie-login/main.cpp @@ -6,9 +6,12 @@ #include #include #include +#include #include #include +#include +#include #include @@ -17,134 +20,162 @@ #include "loginwindowimpl.h" #include "calibrate.h" - + int login_main ( int argc, char **argv ); +void sigusr1 ( int sig ); +void exit_closelog ( ); + int main ( int argc, char **argv ) { - if ( geteuid ( ) != 0 ) { - fprintf ( stderr, "%s can only be executed by root.
