Void - Why would someone do this if void returns nothing?

Projects Programming

I have a sketch with this line in it

void httpGet(String ip, String path, int port=80);

And after reading this thread.....

http://forum.arduino.cc/index.php?topic=215085.0

I'm still not sure the point or purpose of that line in the sketch

What use does this line serve in ANY sketch?

It's a function prototype with one defaulted argument.

The answer would be in the source code for the httpGet() function, which you have access to.

Edit:
Oops, my bad. Missed the variable types in the parameter list. It is a prototype. But, answer is still the same, look at the function's source code.

Excellent and thanks.

Now that I know it's called a "Function Prototype" I can do my research.
