DbEnv::set_msgfile(FILE *msgfile);

void
DbEnv::get_msgfile(FILE **msgfilep);

Description: DbEnv::set_msgfile

There are interfaces in the Berkeley DB library which either directly output informational messages or statistical information, or configure the library to output such messages when performing other operations, for example, DbEnv::set_verbose and DbEnv::stat_print.

The DbEnv::set_msgfile and Db::set_msgfile methods are used to display these messages for the application. In this case, the message will include a trailing <newline> character.

Setting msgfile to NULL unconfigures the interface.

Alternatively, you can use the DbEnv::set_message_stream and Db::set_message_stream methods to display the messages via an output stream, or the DbEnv::set_msgcall and Db::set_msgcall methods to capture the additional error information in a way that does not use either output streams or C library FILE *'s. You should not mix these approaches.

The DbEnv::set_msgfile method may be called at any time during the life of the application.

Parameters

msgfile

The msgfile parameter is a C library FILE * to be used for displaying messages.

Description: DbEnv::get_msgfile

The DbEnv::get_msgfile method returns the .

The DbEnv::get_msgfile method may be called at any time during the life of the application.
