Check for the existence of a record in a tdb database
#include <tdb.h> int tdb_exists(TDB_CONTEXT *tdb, TDB_DATA key);
Test to see if a key exists. tdb is a pointer returned by tdb_open and key is a lump of data that is used as the index into the database. The TDB_DATA structure is defined as:
typedef struct {
char *dptr;
size_t dsize;
} TDB_DATA;
If the key is found, 1 is returned; otherwise 0 is returned.
