c - 我在修补 DWM 时遇到错误，此处不允许使用有关函数定义的内容

Question

我正在尝试在 dwm 中获取系统托盘。 DWM是suckless的X动态窗口管理器:https://dwm.suckless.org/ 。要配置 dwm，您需要自己手动添加补丁。我制作了一个包含所有文件的 git 存储库，位于 https://github.com/domianter34/dwm/tree/master/dwm ，但问题似乎仅与 dwm.c 文件有关。另外，在我添加的 git 存储库中，我包含了我添加过的所有补丁，因此我没有针对库存 dwm 对其进行修补。我也在 FreeBSD 上编译这个，但我认为操作系统与这个问题无关。预先感谢您。

我对 C 编程一无所知，所以我在这里问。从我读到的有关错误的内容来看，它似乎表明我在某处缺少括号，但在该行它也指出了我，一切似乎都按顺序进行。

这是确切的错误:

我想要的是它在应用补丁的情况下成功编译，这样我就可以使用系统托盘。

我看到的第一个错误:

关于:

void
expose(XEvent *e)
{
    Monitor *m;
    XExposeEvent *ev = &e->xexpose;

    if (ev->count == 0 && (m = wintomon(ev->window))) { 
        drawbar(m);
        if (m == selmon)
                   updatesystray();
}

仔细重写以暴露问题:

void
expose(XEvent *e)
{
    Monitor *m;
    XExposeEvent *ev = &e->xexpose;

    if (ev->count == 0 && (m = wintomon(ev->window))) 
    {   
        drawbar(m);
        if (m == selmon)
                       updatesystray();
    }
// this is missing, right here,  the final closing brace '}'
