NAME
cdb_seek -- search for a key in a constant database
SYNOPSIS
#include <freecdb.h>
int cdb_seek(int fd, char *key, unsigned int len, uint32 *dlen);
DESCRIPTION
cdb_seek looks up the key key of length len from the constant database open on file descriptor fd.
On success, it seeks fd to the start of key value, and sets dlen to the value size.
RETURN VALUE
1 on a match, 0 on a miss, -1 on error.
RESTRICTIONS
There is no way to read multiple records with the same key.
Seeking modifes the location of the file descriptor. Don't try to do simultaneous searches.
Updates to the constant database will only be seen after a close(2) and open(2).
