Berkeley DB: Db::set_errpfx
Db::set_errpfx
|
 
|
#include <db_cxx.h>
void Db::set_errpfx(const char *errpfx);
Description
Set the prefix string that appears before error messages issued by Berkeley DB.
The Db::set_errpfx and DbEnv::set_errpfx methods do not copy
the memory to which the errpfx argument 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.
For Db handles opened inside of Berkeley DB environments, calling the
Db::set_errpfx method affects the entire environment and is equivalent to calling
the DbEnv::set_errpfx method.
The Db::set_errpfx interface may be used to configure Berkeley DB at any time
during the life of the application.
