c - 修补DWM时遇到错误，此处不允许有关函数定义的某些内容

我正在尝试在dwm中获得系统托盘。 DWM是X的动态窗口管理器：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git repo，其中包含位于https://github.com/domianter34/dwm/tree/master/dwm的所有文件，但是问题似乎仅在于dwm.c文件。同样，在git repo中，我添加了我曾经添加的所有补丁，所以我没有针对stock dwm对其进行补丁。我也在FreeBSD上进行编译，但是我认为OS与这个问题无关。先感谢您。

我不知道有关C编程的第一件事，因此我为什么要在这里问。从我读到的有关错误的内容来看，似乎表明我在某处缺少括号，但从直线上也可以看出一切似乎井井有条。

这是确切的错误：

我想要的是它能够成功应用补丁程序进行编译，因此我可以使用系统托盘。

最佳答案

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 '}'
