+/**
+ * tdb - The trivial (transactional) database
+ *
+ * The tdb module provides an efficient keyword data mapping (usually
+ * within a file).  It supports transactions, so the contents of the
+ * database is reliable even across crashes.
+ *
+ * Example:
+ *     #include <ccan/tdb/tdb.h>
+ *     #include <ccan/str/str.h>
+ *     #include <err.h>
+ *     #include <stdio.h>
+ *     
+ *     static void usage(void)
+ *     {
+ *             errx(1, "Usage: %s fetch <dbfile> <key>\n"
+ *                  "OR %s store <dbfile> <key> <data>");
+ *     }
+ *     
+ *     int main(int argc, char *argv[])
+ *     {
+ *             struct tdb_context *tdb;
+ *             TDB_DATA key, value;
+ *     
+ *             if (argc < 4)
+ *                     usage();
+ *     
+ *             tdb = tdb_open(argv[2], 1024, TDB_DEFAULT, O_CREAT|O_RDWR,
+ *                             0600);
+ *             if (!tdb)
+ *                     err(1, "Opening %s", argv[2]);
+ *     
+ *             key.dptr = (void *)argv[3];
+ *             key.dsize = strlen(argv[3]);
+ *     
+ *             if (streq(argv[1], "fetch")) {
+ *                     if (argc != 4)
+ *                             usage();
+ *                     value = tdb_fetch(tdb, key);
+ *                     if (!value.dptr)

+ *                     printf("%.*s\n", value.dsize, (char *)value.dptr);
+ *                     free(value.dptr);
+ *             } else if (streq(argv[1], "store")) {
+ *                     if (argc != 5)
+ *                             usage();
+ *                     value.dptr = (void *)argv[4];
+ *                     value.dsize = strlen(argv[4]);
+ *                     if (tdb_store(tdb, key, value, 0) != 0)
