CONF_modules_free(3)

     NAME
           CONF_modules_free, CONF_modules_load, CONF_modules_unload -
           OpenSSL configuration cleanup functions


     SYNOPSIS
           #include <openssl/conf.h>

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


     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.
