Problems with ndbm

[doug at zaphod.prime.com]

I judged that the storage used in the dptr value was probably reused.  I hadn't
made assumptions about the persistance of datum -> dptr. What happens is
something like:

datum *x;

x = dbm_fetch(thedb, thekey);

x -> dptr[x -> dsize] = '\0';

printf("%s\n", x -> dptr);  // Something is printed

x = dbm_fetch(thedb, thekey);

x -> dptr[x -> dsize] = '\0';

printf("%s\n", x -> dptr);  // Null is printed
