I'd like to define a C function that takes two arguments of type
"array of <fixed-length type>" and returns an INT4.  The function
would make use of the <, <=, =, >=, > operators on the base type.  Any
examples of or documentation on how to:

1.  Extract information about the underlying type from the arrays, in   particular the size of the type?

2.  Apply an operator from within C?
