Berkeley DB: DbEnv::set_errpfx
DbEnv::set_errpfx
|
 |
#include <db_cxx.h>
void
DbEnv::set_errpfx(const char *errpfx);
void
DbEnv::get_errpfx(const char **errpfxp);
Description: DbEnv::set_errpfx
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 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 DbEnv::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: DbEnv::get_errpfx
The DbEnv::get_errpfx method returns the error prefix.
The DbEnv::get_errpfx method may be called at any time during the life of the
application.
The DbEnv::get_errpfx method
either returns a non-zero error value
or throws an exception that encapsulates a non-zero error value on
failure, and returns 0 on success.
Parameters
- errpfxp
- The DbEnv::get_errpfx method returns a reference to the
error prefix in errpfxp.
