The
<ndbm.h> header shall define the
datum type as a
structure that includes at least the following members:
void *dptr A pointer to the application's data.
size_t dsize The size of the object pointed to by dptr.
The
size_t type shall be defined as described in
<stddef.h>
.
The

DBM type.
The following constants shall be defined as possible values for the
store_mode argument to
dbm_store():
- DBM_INSERT
- Insertion of new entries only.
- DBM_REPLACE
- Allow replacing existing entries.
The following shall be declared as functions and may also be defined as macros.
Function prototypes shall be provided.
int dbm_clearerr(DBM *);
void dbm_close(DBM *);
int dbm_delete(DBM *, datum);
int dbm_error(DBM *);
datum dbm_fetch(DBM *, datum);
datum dbm_firstkey(DBM *);
datum dbm_nextkey(DBM *);
DBM *dbm_open(const char *, int, mode_t);
int dbm_store(DBM *, datum, datum, int);
The
