TDB_EXISTS(3) Linux Programmer's Manual TDB_EXISTS(3)

tdb_exists - 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.
