SYNTAX

11
12       int cdb_find(struct cdb *c,char *key,unsigned long int keylen);
13       int cdb_datalen(struct cdb *c);
14       int cdb_datapos(struct cdb *c);
15       int cdb_findnext(struct cdb *c,char *key,unsigned long int keylen);

DESCRIPTION

19       cdb_find  looks  for  key. If cdb_find returns 0, the database does not
20       contain that key; stop. If cdb_find returns -1, there was a read error;
21       abort.
22
23       cdb_datalen  returns  the  length  of the data associated with the key.
24       Use it to allocate a pointer p with enough space to hold the data.
25
26       cdb_datapos returns the position of the data inside the file.   Use  it
27       as argument to cdb_read to retrieve the data.
28
29       There  may be several records under a single key. You can use cdb_find‐
30       next to find the next record under this key.

EXAMPLE

34       static struct c;
35
36       if (cdb_find(&c,key,strlen(key)>0) {
37         char *buf=alloca(cdb_datalen(&c));
38         cdb_read(&c,buf,cdb_datalen(&c),cdb_datapos(&c));
39         write(1,buf,cdb_datalen(&c));
40       }
