Changing number of streams at run time

[bigginsking]

I have this work so that I can write to a UART and SD card, and that works fantastic but when the SD isn't available at start up the UART out fails. Here are the relevant bits of code:

HardwareSerial & Ser = Serial3; //rename the serial to make the code more flexible
Print *serout[2] = {&Ser, &dataFile }; //put the Serial outputs together?
NeoTee SerSd(serout, sizeof(serout)/sizeof(serout[0])); //wish better understood this...

void setup() 
{
SPI.swap(1);
if (!SD.begin(17)) {
Ser.println("SD initialization failed!");
sdavail = false;
//Print *serout[1] = {&Ser }; //put the Serial 
NeoTee SerSd(serout, sizeof(serout[0])/sizeof(serout[0])); //I would think this would work but it doesn't
//HardwareSerial & SerSd = Serial3; //This doesn't work either
}
}

Is there a way that I can get this to work with and without the SD card present?
