 To use these data structures, you include the desired header,
 instantiate the definition of the structure and its associated methods by using a macro _DEF.

+This looks like a typical C program except the line with 'LIST\_DEF'

+this line, everything is typical C program and even macro free!
+The only macro is in fact LIST\_DEF: this macro expands to the

+You can use it as many times as needed to defined as many lists as you want.
