Multidimensional arrays of function pointers

Embedded hardware often contains an application processor and one or more additional processors attached to the printed circuit board.  The firmware that resides on the adjacent processor(s) responds to a series of processor specific instructions.

High-volume, parallel testing of firmware can be achieved using function-like macros and arrays of function pointers, where function name lookup occurs in constant time.  A fast scanner written in C using a finite automata in conjunction with a parser, also written in C, can be used for reading tests based on a custom context-free grammar. Dynamic arrays of function pointers can then be allocated at run-time and code within external object files or libraries can be executed in parallel using multiple processes or threads.

I wrote the following C code which is based on prior client work.  The code uses arrays of function pointers for executing functions via their addresses.
