CONF_MODULES_FREE(3SSL) OpenSSL CONF_MODULES_FREE(3SSL)
NAME
CONF_modules_free, CONF_modules_finish, CONF_modules_unload - OpenSSL
configuration cleanup functions
SYNOPSIS
#include <openssl/conf.h>
void CONF_modules_finish(void);
void CONF_modules_unload(int all);
The following functions have been deprecated since OpenSSL 1.1.0, and
can be hidden entirely by defining OPENSSL_API_COMPAT with a suitable
version value, see openssl_user_macros(7):
void CONF_modules_free(void);
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 finish handler to
free up any configuration that module may have performed.
CONF_modules_unload() finishes and unloads configuration modules. If all
is set to 0 only modules loaded from DSOs will be unloads. If all is 1
all modules, including built-in modules will be unloaded.
RETURN VALUES
None of the functions return a value.
