巨集的定義：

vlc_module_begin ()
    set_description( N_("HTTP stream output") )
    set_capability( "sout access", 0 )
    set_shortname( "HTTP" )
    add_shortcut( "http", "https", "mmsh" )
    set_category( CAT_SOUT )
    set_subcategory( SUBCAT_SOUT_ACO )
    add_string( SOUT_CFG_PREFIX "user", "",
                USER_TEXT, USER_LONGTEXT, true )
    add_password( SOUT_CFG_PREFIX "pwd", "",
                  PASS_TEXT, PASS_LONGTEXT, true )
    add_string( SOUT_CFG_PREFIX "mime", "",
                MIME_TEXT, MIME_LONGTEXT, true )
    add_bool( SOUT_CFG_PREFIX "metacube", false,
              METACUBE_TEXT, METACUBE_LONGTEXT, true )
    set_callbacks( Open, Close )
vlc_module_end ()

巨集展開後：展開方式，VS中屬性－〉C/C++/前處理器：預處理到檔案　選擇　是　編譯後在相應的工程檔案目錄下有*.i檔案，從中可取出以下巨集的展開部分。例子裡是VLC2.2.6
