Resizable Buffers

A buffer of type T is a dynamically allocated array with elements of type T, together with variable of type "int" that says how large the buffer is (measured array elements).

Buffers are such a common pattern in C programming that it is convenient to implement the basic mechanics in a library.

The crux "ar" library interface needs only two functions: ar_ref (to access an element, given its index, enlarging the array on-demand if necessary); ar_trim (to reduce the size of a buffer, discrarding elements from the end of the buffer if necessary).

crux n., pl. cruxes or cruces. 1. A crucial or vital moment; critical point. 2. The basic or essential thing. 3. A puzzling problem.
