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.
