Conformant Arrays in C

[Roy Smith]

	I'm not sure I follow all the details of David's note, but I
thought I would throw in my suggestion anyway.  Some time ago I had need
for variable-dimension arrays in C.  What I ended up using was vectored
arrays.  I wrote an array allocator which called malloc to get memory for
the main array and for the row address vector, and which initialized the
vector to point to the right places in the main array.  After that, you
could pretend you had a variable dimensional array; i.e. you could pass a
subroutine the pointer returned by arrayalloc and the dimensions you used.
It was posted a few years back to mod.sources.
