パラメーター

名前	型	方向	説明
hNamedPipe	HANDLE	in	書き込みと読み取りを一括で行う名前付きパイプのハンドルを指定する。
lpInBuffer	void*	inoptional	パイプへ書き込むデータを格納したバッファを指定する。
nInBufferSize	DWORD	in	lpInBufferのサイズ(バイト)を指定する。
lpOutBuffer	void*	outoptional	パイプから読み取った応答データを受け取るバッファを指定する。
nOutBufferSize	DWORD	in	lpOutBufferのサイズ(バイト)を指定する。
lpBytesRead	DWORD*	out	lpOutBufferへ読み取られたバイト数を受け取る出力先。
lpOverlapped	OVERLAPPED*	inoutoptional	非同期処理に使うOVERLAPPED構造体。同期動作ではNULL可。
