A macro is not a function. It is some code replaced by some other code at 
compilation time. The "getmaxyx" identifier does not exist in the executable.

You must read the C header file to see what the getmaxyx() macro actually 
does.

The gcc compiler has the "-E" option that can help you, by writing to the 
standard output the real code that will be compiled once all macros have been 
expanded.
