=pod =head1 NAME CONF_modules_free, CONF_modules_finish, CONF_modules_unload - OpenSSL configuration cleanup functions =head1 SYNOPSIS #include <openssl/conf.h> void CONF_modules_free(void); void CONF_modules_finish(void); void CONF_modules_unload(int all); =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<finish> handler to free up any configuration that module may have performed. CONF_modules_unload() finishes and unloads configuration modules. If B<all> is set to B<0> only modules loaded from DSOs will be unloads. If B<all> is B<1> all modules, including builtin modules will be unloaded. =head1 NOTES Normally applications will only call CONF_modules_free() at application to tidy up any configuration performed. =head1 RETURN VALUE None of the functions return a value. =head1 SEE ALSO L<conf(5)|conf(5)>, L<OPENSSL_config(3)|OPENSSL_config(3)>, L<CONF_modules_load_file(3), CONF_modules_load_file(3)> =head1 HISTORY CONF_modules_free(), CONF_modules_unload(), and CONF_modules_finish() first appeared in OpenSSL 0.9.7. =cut
