# NAME

CONF_modules_free, CONF_modules_finish, CONF_modules_unload - OpenSSL configuration cleanup functions

# SYNOPSIS

     #include <openssl/conf.h>

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

Deprecated:

     #if OPENSSL_API_COMPAT < 0x10100000L
     void CONF_modules_free(void)
     #endif

# DESCRIPTION

`CONF_modules_free()` closes down and frees up all memory allocated by all configuration modules. Normally, in versions of OpenSSL prior to 1.1.0, applications called `CONF_modules_free()` at exit to tidy up any configuration performed.

`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.

# RETURN VALUES

None of the functions return a value.

# SEE ALSO

config(5), OPENSSL_config(3), CONF_modules_load_file(3)

# HISTORY

`CONF_modules_free()` was deprecated in OpenSSL 1.1.0; do not use it. For more information see OPENSSL_init_crypto(3).
