=pod =head1 NAME CONF_modules_free, CONF_modules_finish, CONF_modules_unload - OpenSSL configuration cleanup functions =head1 SYNOPSIS #include void CONF_modules_finish(void); void CONF_modules_unload(int all); Deprecated: #if OPENSSL_API_COMPAT < 0x10100000L void CONF_modules_free(void) #endif =head1 DESCRIPTION CONF_modules_free() closes down and frees up all memory allocated by all configuration modules. CONF_modules_finish() calls each configuration modules B handler to free up any configuration that module may have performed. CONF_modules_unload() finishes and unloads configuration modules. If B is set to B<0> only modules loaded from DSOs will be unloads. If B is B<1> all modules, including builtin modules will be unloaded. =head1 NOTES Normally in versions of OpenSSL prior to 1.1.0 applications will only call CONF_modules_free() at application exit to tidy up any configuration performed. From 1.1.0 CONF_modules_free() is deprecated and no explicit CONF cleanup is required at all. For more information see L. =head1 RETURN VALUE None of the functions return a value. =head1 SEE ALSO L, L, L =head1 HISTORY CONF_modules_free() was deprecated in OpenSSL 1.1.0. =head1 COPYRIGHT Copyright 2004-2016 The OpenSSL Project Authors.
