一共 6 個(gè)函數(shù),
RegisterDriver 注冊(cè)驅(qū)動(dòng)到注冊(cè)表.
UnregisterDriver 從注冊(cè)表注銷驅(qū)動(dòng).
RunDriver 運(yùn)行驅(qū)動(dòng).
StopDriver 停止驅(qū)動(dòng)的運(yùn)行.
ControlDriver 向正在運(yùn)行的驅(qū)動(dòng)發(fā)送 I/O Control 控制碼.
GetLastErrorDescription 取得上述 5 個(gè)操作時(shí)遭遇到的錯(cuò)誤, 只能取得最近的那個(gè)錯(cuò)誤
以下是源代碼
