   8 =head1 SYNOPSIS
   9
  10  #include <openssl/conf.h>
  11
  12  void CONF_modules_finish(void);
  13  void CONF_modules_unload(int all);
  14
  15 The following functions have been deprecated since OpenSSL 1.1.0, and can be
  16 hidden entirely by defining B<OPENSSL_API_COMPAT> with a suitable version value,
  17 see L<openssl_user_macros(7)>:
  18
  19  void CONF_modules_free(void);

  21 =head1 DESCRIPTION
  22
  23 CONF_modules_free() closes down and frees up all memory allocated by all
  24 configuration modules.  Normally, in versions of OpenSSL prior to 1.1.0,
  25 applications called
  26 CONF_modules_free() at exit to tidy up any configuration performed.
  27
  28 CONF_modules_finish() calls each configuration modules B<finish> handler
  29 to free up any configuration that module may have performed.
  30
  31 CONF_modules_unload() finishes and unloads configuration modules. If
  32 B<all> is set to B<0> only modules loaded from DSOs will be unloads. If
  33 B<all> is B<1> all modules, including built-in modules will be unloaded.

  35 =head1 RETURN VALUES
