Usage example:

voidsetup() {  Serial.begin(9600);}staticint loop_cnt =0;voidloop() {  Serial.printf  ("[%d]",millis());   Serial.printfln("Loop Cnt %d", loop_cnt);  loop_cnt++;delay(1000);  }

Output:

[0] Loop Cnt 0[999] Loop Cnt 1[199] Loop Cnt 2...

The function can't be namedprint because in this case its signature overlaps withsize_t print(const char[]) (No variadic arguments is a legimitate use case).

This seems like a duplicate of#28, which IMHO has a better implementation that has no fixed-size buffer. So I'm going to go ahead and close this PR, to keep things a bit more tidy (also since this feature is a bit controversial, as discussed in#32 and#28).
