Berkeley DB: DB->set_msgfile
DB->set_msgfile
|
 |
#include <db.h>
void
DB->set_msgfile(DB *db, FILE *msgfile);
void
DB->get_msgfile(DB *db, FILE **msgfilep);
Description: DB->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, DB_ENV->set_verbose and DB_ENV->stat_print.
The DB_ENV->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 DB_ENV->set_msgcall or
DB->set_msgcall methods to capture the additional error information
in a way that does not use C library FILE *'s.
For DB handles opened inside of Berkeley DB environments, calling the
DB->set_msgfile method affects the entire environment and is equivalent to calling
the DB_ENV->set_msgfile method.
The DB->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: DB->get_msgfile
The DB->get_msgfile method returns the .
The DB->get_msgfile method may be called at any time during the life of the
application.
