id is a preprocessor identifier, code is valid C source code.
This directive acts much like the #IF except that the preprocessor simply checks
to see if the specified ID is known to the preprocessor (created with a #DEFINE).
#IFDEF checks to see if defined and #IFNDEF checks to see if it is not defined.
