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.
