- =head1 NAME
- CONF_modules_free, CONF_modules_finish, CONF_modules_unload -
- OpenSSL configuration cleanup functions
- =head1 SYNOPSIS
- #include <openssl/conf.h>
- void CONF_modules_free(void);
- void CONF_modules_finish(void);
- void CONF_modules_unload(int all);
- =head1 DESCRIPTION
- CONF_modules_free() closes down and frees up all memory allocated by all
- configuration modules.
- CONF_modules_finish() calls each configuration modules B<finish> handler
- to free up any configuration that module may have performed.
- CONF_modules_unload() finishes and unloads configuration modules. If
- B<all> is set to B<0> only modules loaded from DSOs will be unloads. If
- B<all> is B<1> all modules, including builtin modules will be unloaded.
- =head1 NOTES
- Normally applications will only call CONF_modules_free() at application to
- tidy up any configuration performed.
- =head1 RETURN VALUE
- None of the functions return a value.
