qt串口通信发送0X00（'\0' NULL）问题解决提示

 

  static const char mydata[] = { 0x00, 0x00, 0x03, 0x84, 0x78, 0x9c, 0x3b, 0x76, 0xec, 0x18, 0xc3, 0x31, 0x0a, 0xf1, 0xcc, 0x99, ... 0x6d, 0x5b };  data = ::fromRawData(mydata, sizeof(mydata));  in(&data, QIODevice::ReadOnly); ...

Warning: A byte array created with fromRawData() is not null-terminated, unless the raw data contains a 0 character at position size. While that does not matter for  or functions like (), passing the byte array to a function accepting a const char * expected to be '\0'-terminated will fail.
