.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBCONF_modules_free()\fR closes down and frees up all memory allocated by all
configuration modules.  Normally, in versions of OpenSSL prior to 1.1.0,
applications called
\&\fBCONF_modules_free()\fR at exit to tidy up any configuration performed.
.PP
\&\fBCONF_modules_finish()\fR calls each configuration modules \fBfinish\fR handler
to free up any configuration that module may have performed.
.PP
\&\fBCONF_modules_unload()\fR finishes and unloads configuration modules. If
\&\fBall\fR is set to \fB0\fR only modules loaded from DSOs will be unloads. If
\&\fBall\fR is \fB1\fR all modules, including builtin modules will be unloaded.
