虛擬鍵盤(pán)驅(qū)動(dòng)程序

1、虛擬鍵盤(pán)驅(qū)動(dòng)程序作者聯(lián)系方式：李先靜前段時(shí)間寫(xiě)一個(gè)程序，要向系統(tǒng)中注入按鍵事件，我又不想信賴(lài)于具體的GUI,就寫(xiě)一個(gè)虛 擬鍵盤(pán)設(shè)備驅(qū)動(dòng)程序，感覺(jué)挺好用的，不過(guò)后來(lái)發(fā)現(xiàn)linux其實(shí)有一個(gè)uinput驅(qū)動(dòng)程序?qū)崿F(xiàn) 了類(lèi)似的功能。幸好后來(lái)才發(fā)現(xiàn)uinput這玩意兒，否則就沒(méi)有機(jī)會(huì)去寫(xiě)了這個(gè)程序了，有 時(shí)真是寧愿知識(shí)面窄一點(diǎn)，這樣才有機(jī)會(huì)重復(fù)發(fā)明一些輪子，從中獲得一些樂(lè)趣。o先寫(xiě)一個(gè)字符驅(qū)動(dòng)程序。#include #include #include #include #include #include #include #include #include #include #include #inc
