class DbMemoryException : public DbException { DbMemoryException(Dbt *dbt); DbMemoryException(const char *description); DbMemoryException(const char *prefix, Dbt *dbt); DbMemoryException(const char *prefix1, const char *prefix2, Dbt *dbt); Dbt *get_dbt() const; };

Description

This manual page describes the DbMemoryException class and how it is used by the various Db* classes.

A DbMemoryException is thrown when there is insufficient memory to complete an operation, and there is the possibility of recovering. An example is during a Db::get or Dbc::get operation with the Dbt flags set to DB_DBT_USERMEM. In this case, the DbMemoryException::get_dbt method returns the problematic Dbt, and the operation can be retried with a larger buffer.
