C语言通过DBUS库调用"org.dharkael.kylinscreenshot"和"org.dharkael.kylinscreenshot.xml"实现截图完整demo

你可以使用以下代码来实现C语言通过DBUS库调用"org.dharkael.kylinscreenshot"和"org.dharkael.kylinscreenshot.xml"来实现截图的完整demo：

#include <stdio.h>
#include <dbus/dbus-glib.h>

static void take_screenshot(DBusGProxy *proxy) {
    GError *error = NULL;
    gchar *result = NULL;

    if (!dbus_g_proxy_call(proxy, "take_screenshot", &error, G_TYPE_INVALID, G_TYPE_STRING, &result, G_TYPE_INVALID)) {
        if (error != NULL) {
            printf("DBus call error: %s\n", error->message);
            g_error_free(error);
        }
    } else {
        printf("Screenshot saved to: %s\n", result);
        g_free(result);
    }
}

int main() {
    GError *error = NULL;
    DBusGConnection *connection;
    DBusGProxy *proxy;

    // Connect to the session bus
    connection = dbus_g_bus_get(DBUS_BUS_SESSION, &error);
    if (error != NULL) {
        printf("DBus connection error: %s\n", error->message);
        g_error_free(error);
        return 1;
    }

    // Create a proxy object for the "org.dharkael.kylinscreenshot" service
    proxy = dbus_g_proxy_new_for_name(connection, "org.dharkael.kylinscreenshot", "/org/dharkael/kylinscreenshot", "org.dharkael.kylinscreenshot");
    if (proxy == NULL) {
        printf("Failed to create DBus proxy\n");
        return 1;
    }

    // Call the take_screenshot method
    take_screenshot(proxy);

    // Clean up
    g_object_unref(proxy);
    dbus_g_connection_unref(connection);

    return 0;
}

请确保你已经安装了DBUS库，并将代码中的"org.dharkael.kylinscreenshot"和"org.dharkael.kylinscreenshot.xml"替换为你要调用的DBUS服务和对应的XML文件。
