IOCTL_SERIAL_SET_TIMEOUTS请求设置串行控制器驱动程序用于读取和写入请求的超时值。 若要获取超时值,客户端可以使用IOCTL_SERIAL_GET_TIMEOUTS请求。 有关超时的详细信息,请参阅为串行设备设置读取和写入 Time-Outs。 主要代码 IRP_MJ_DEVICE_CONTROL 输入缓冲区 ...
[in] Set to this IOCTL: IOCTL_SERIAL_SET_TIMEOUTS. pBufIn [in] Pointer to aCOMMTIMEOUTSstructure. dwLenIn [in] Set tosizeof(COMMTIMEOUTS). pBufOut Ignored. dwLenOut Ignored. pdwActualOut Ignored. Return Values Returns TRUE if successful. Returns FALSE otherwise. To get extended error infor...
The IOCTL_SERIAL_SET_TIMEOUTS request sets the time-out values that the serial controller driver uses for read and write requests.To get the time-out values, a client can use an IOCTL_SERIAL_GET_TIMEOUTS request.For more information about time-outs, see Setting Read and Write Time-Outs for...
