There are interfaces in the m4_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, m4_ref(dbenv_set_verbose) and m4_ref(dbenv_stat_print).])

The m4_ref(dbenv_set_message_stream) and
|
|
m4_refT(dbh_set_message_stream)s are used to display these messages for
|
|
the application. In this case, the message will include a trailing
|
|
m4_htmlquote(newline) character.])

Alternatively, you can use the m4_ref(dbenv_set_msgfile) and
|
|
m4_refT(dbh_set_msgfile)s to display the messages via a C library FILE *,
|
|
or the m4_ref(dbenv_set_msgcall) and m4_refT(dbh_set_msgcall)s 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.])
