Description

The hsearch interface to the Berkeley DB library is intended to provide a high-performance implementation and source code compatibility for applications written to the historic hsearch interface. It is not recommended for any other purpose.

To compile hsearch applications, replace the application’s #include of the hsearch include file (for example, #include <search.h>) with the following two lines:

#define DB_DBM_HSEARCH     1 
#include <db.h> 

and recompile.

The hcreate function creates an in-memory database. ...
