simply do nothing\&.

\fBsd_journal_add_match()\fR,
\fBsd_journal_add_disjunction()\fR
and

always return 0\&.
\fBsd_journal_flush_matches()\fR
returns nothing\&.
.SH "NOTES"
.PP
These APIs are implemented as a shared library, which can be compiled and linked to with the
\fBlibelogind\fR\ \&\fBpkg-config\fR(1)
file\&.
