# NAME

OPENSSL_load_builtin_modules - add standard configuration modules

# SYNOPSIS

     #include <openssl/conf.h>

     void OPENSSL_load_builtin_modules(void);
     void ASN1_add_oid_module(void);
     ENGINE_add_conf_module();

# DESCRIPTION

The function `OPENSSL_load_builtin_modules()` adds all the standard OpenSSL configuration modules to the internal list. They can then be used by the OpenSSL configuration code.

ASN1_add_oid_module() adds just the ASN1 OBJECT module.

`ENGINE_add_conf_module()` adds just the ENGINE configuration module.

# NOTES

If the simple configuration function `OPENSSL_config()` is called then `OPENSSL_load_builtin_modules()` is called automatically.

Applications which use the configuration functions directly will need to call `OPENSSL_load_builtin_modules()` themselves before any other configuration code.

Applications should call `OPENSSL_load_builtin_modules()` to load all configuration modules instead of adding modules selectively: otherwise functionality may be missing from the application if an when new modules are added.

# RETURN VALUE

None of the functions return a value.

# SEE ALSO

conf(3), OPENSSL_config(3)

# HISTORY

These functions first appeared in OpenSSL 0.9.7.
