<font size="4">
<font size="5" color="#0000FF"><strong>功能：</strong></font>
这个函数用于检测是否有鼠标点击事件发生并立即返回。
当执行该函数并且检测到鼠标点击事件后，执行delay_fps/delay_ms/delay_jfps函数会清除鼠标点击状态。

<font size="5" color="#0000FF"><strong>声明：</strong></font>
<pre><font color=#0000FF>int </font><font color=#008080>mousepressed</font>();</pre>
<font size="5" color="#0000FF"><strong>参数：</strong></font>
（无）

<font size="5" color="#0000FF"><strong>返回值：</strong></font>
如果有鼠标点击发生，返回 1；否则返回 0。

<font size="5" color="#0000FF"><strong>示例：</strong></font>
#include <graphics.h>

int main() {
initgraph(800,600);
setrendermode(RENDER_MANUAL);


int count = 0;
for(;is_run();delay_fps(60)) {
if (mousepressed()) {
//检测到鼠标点击事件
count += 1;
//清除屏幕原有内容，然后输出点击提示
cleardevice();
xyprintf(50,50,"clicked %d times",count);
}
}
closegraph();
return 0;
}
