在阅读这个函数的帮助时,下面这两句,我翻译不了,谁帮忙看一下。
2. If an IOCTL caller passes in otherwise correct parameters with a buffer that is too small (as determined by examining nOutSize), we will fail with ERROR_INSUFFICIENT_BUFFER and return *pOutSize = minimum buffer size necessary for success.
3. If an IOCTL caller passes in correct parameters with a sufficient buffer (nOutSize >= necessary size), we will return *pOutSize = # of bytes in the buffer that we actually filled upon completion (regardless of success or failure).
