For example, you will be able to open * URLs via native mozilla if no browser has yet been installed in wine. * * The application to launch is chosen from a default set or, if set, * taken from a registry key. * * The argument may be a regular Windows file name, a file URL, an * URL or a mailto URL. In the first three cases the argument * will be fed to a web browser. In the last case the argument is fed * to a mail client. A mailto URL is composed as follows: * * mailto:[E-MAIL]?subject=[TOPIC]&cc=[E-MAIL]&bcc=[E-MAIL]&body=[TEXT] */ #define WIN32_LEAN_AND_MEAN #define COBJMACROS #include "config.h" #include "wine/port.h" #include "wine/debug.h" #include "wine/unicode.h" #include <windows.h> #include <shlwapi.h> #include <shellapi.h> #include <urlmon.h> #include <ddeml.h> #include <stdio.h> #include <stdlib.h> #include <errno.h> WINE_DEFAULT_DEBUG_CHANNEL(winebrowser);
