Yes, I want to get the completions and their
descriptions generically so that I can use zaw as an
alternative method for performing completions.

After poking around the source code some more it seems
that amatches[i]->matches[j]->str should contain the
completions (for different values of i and j). However
when I try exploring that datastructure at breakpoints
in the printlist, ilistmatches, and complistmatches
functions gdb tells me: "Cannot access memory at address 0x0" 
I get the same message when I try pmatches.

Any more advice?
