void
DB_ENV->set_errpfx(DB_ENV *dbenv, const char *errpfx);

void
DB_ENV->get_errpfx(DB_ENV *dbenv, const char **errpfxp);

Description: DB_ENV->set_errpfx

Set the prefix string that appears before error messages issued by Berkeley DB.

The DB->set_errpfx and DB_ENV->set_errpfx methods do not copy the memory to which the errpfx parameter refers; rather, they maintain a reference to it. Although this allows applications to modify the error message prefix at any time (without repeatedly calling the interfaces), it means the memory must be maintained until the handle is closed.

The DB_ENV->set_errpfx method may be called at any time during the life of the application.

Parameters

errpfx

The errpfx parameter is the application-specified error prefix for additional error messages.

Description: DB_ENV->get_errpfx

The DB_ENV->get_errpfx method returns the error prefix.

The DB_ENV->get_errpfx method may be called at any time during the life of the application.

The DB_ENV->get_errpfx method returns a non-zero error value on failure and 0 on success.

Parameters

errpfxp

The DB_ENV->get_errpfx method returns a reference to the error prefix in errpfxp.
