NAME

       OPENSSL_load_builtin_modules, ASN1_add_oid_module, ENGINE_add_conf_module - 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.
