I try to pass a column from a table as a parameter to a C function.

The column is an array of float8 with V1 method.
I can't find the method to pick up the arguments-arrays,

the whole thing looks like this:

     ????? how to get  the parameter as a pointer
     and reach 1st, second, etc. element of array?

     float8 *a = PG_GETARG_POINTER(0) ;
     float8 c = *(a+1) ;
     ^^^^^^^^^^^^^^^^^ doesn't give the value of a[2],
                       but an incredible number

Please help me out, or recommend where to find the info (at developers
guide I found nothing like that)
