CONF_modules_free(3)                OpenSSL               CONF_modules_free(3)

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.
