Why this strchr() ?
if (!strncmp(param_buffer, "--t", 3) &&
!strncmp(param_buffer, "--table", strlen(param_buffer))
err();
should work.

If this is needed, I'd suggest
static const char * const t_options[] = {

If this t_options[] thing is really needed i'd try to stick this into
a helper function so we don't have to duplicate this in all 3
incarnations.
Thanks for working on this.
