NAME

        CONF_modules_free, CONF_modules_finish, CONF_modules_unload -
        OpenSSL configuration cleanup functions

SYNOPSIS

        #include <openssl/conf.h>

        void CONF_modules_free(void);
        void CONF_modules_finish(void);
        void CONF_modules_unload(int all);

DESCRIPTION

       CONF_modules_free() closes down and frees up all memory allocated by all configuration
       modules.

       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.

NOTES

       Normally applications will only call CONF_modules_free() at application to tidy up any
       configuration performed.

RETURN VALUE

       None of the functions return a value.
