写一个代码解决Linux下c++ x11粘贴到别的软件导致软件卡死

在Linux下,X Window System(X11)环境中,遇到从文本编辑器或其他应用复制内容然后粘贴到另一个程序导致卡死的情况,可能是由于内存管理或者其他资源同步问题。一个常见的做法是确保正确处理剪贴板数据以及避免阻塞主线程。下面是一个简单的C++示例,使用`xcb`库(跨平台XCB工具包)来处理剪贴板数据,避免可能导致死锁的直接粘贴操作:
```cpp
#include <xcb/xcb.h>
#include <iostream>
// 假设我们已经有了一个连接到X服务器的Display对象display
Display* display;
void handle_clipboard_data(xcb_atom_t format, const char* data, uint32_t len) {
// 这里只是一个基本的处理,实际可能需要根据format解析数据并传递给目标程序
std::cout << "Received clipboard data of type: " << xcb_get_atom_name(display, format) << "\n";
if (len > 0)
std::cout << "Data: " << std::string(data, len) << '\n';
// 防止阻塞线程,可以将数据放入队列或者异步处理
// 调用系统函数发送数据,而不是直接粘贴
send_to_target_program(data, len);
}
void copy_to_clipboard(const char* data, size_t len) {
// 使用xcb提供的API设置剪贴板内容,这里仅作示例
xcb_cutbuffer_request_t request = { .data = data, .length = len };
xcb_send_with_event(display, XCB_CUT_BUFFER_REQUEST, ...);
}
int main() {
// 初始化并获取剪贴板相关的事件处理上下文
xcb_intern_atom_cookie_t atom_cookie = xcb_intern_atom(display, False, "_NET_WM_PASTE");
xcb_intern_atom_reply_t *atom_reply = xcb_intern_atom_reply(display, atom_cookie, NULL);
// 注册剪贴板事件处理器
xcb_generic_event_t* event;
while ((event = xcb_poll_for_event(display)) != NULL) {
if (xcb_event_is_window_unmap(event)) {
// 如果窗口已关闭,停止监听
break;
} else if (xcb_event_type_is(XCB_CLIPBOARD_NOTIFY, event->response.type)) {
xcb_clipboard_notify_event_t* notify = reinterpret_cast<xcb_clipboard_notify_event_t*>(event);
if (notify->selection == atom_reply->atom) {
handle_clipboard_data(notify->target, notify->data, notify->length);
}
}
xcb_free_event(&event);
}
return 0;
}
