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);

       Deprecated:

        #if OPENSSL_API_COMPAT < 0x10100000L
        void CONF_modules_free(void)
        #endif

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 builtin
       modules will be unloaded.

RETURN VALUES

       None of the functions return a value.
