=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 since OpenSSL 1.1.0, can be hidden entirely by defining B with a suitable version value, see L: void CONF_modules_free(void) =head1 DESCRIPTION CONF_modules_free() closes down and frees up all memory allocated by all configuration modules. Normally, in versions of OpenSSL prior to 1.1.0, applications called CONF_modules_free() at exit to tidy up any configuration performed. 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 RETURN VALUES 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; do not use it.
