Hi,
I'm struggling to understand the db(3) function. I am trying to create a
btree with a key and data, yet btreeop(1) only shows data for the
following program. I'd appreciate any help... really.
Marc
#include <sys/stat.h>
#include <db.h>
#include <fcntl.h>
#include <stdio.h>
#include <stdlib.h>
#define PERM_SECURE (S_IRUSR|S_IWUSR|S_IRGRP|S_IROTH)
#define MAX 12
int
main()
{
DB *db;
DBT data, key;
char buf[MAX + 1], keybuf[MAX + 1];
char dbtmp[MAX + 1], dbname[MAX + 1];
(void)snprintf(dbtmp, sizeof(dbtmp), "dev.tmp");
(void)snprintf(dbname, sizeof(dbtmp), "dev.db");
if(!(db = dbopen(dbtmp, O_CREAT|O_EXLOCK|O_RDWR|O_TRUNC,
PERM_SECURE, DB_BTREE, NULL)))
err(1, "%s", dbtmp);
key.data = keybuf;
(void)strcpy(keybuf, "key");
keybuf[3] = '\0';
data.data = buf;
(void)strcpy(buf, "dat");
buf[3] = '\0';
printf("%s\n%s\n", keybuf, buf);
key.size = 4;
data.size = 4;
if ((db->put)(db, &key, &data, 0))
err(1, "dbput %s", dbtmp);
(void)(db->close)(db);
if (rename(dbtmp, dbname))
err(1, "rename %s to %s", dbtmp, dbname);
exit(0);
}
