# NAME

OPENSSL_load_builtin_modules, ASN1_add_oid_module, ENGINE_add_conf_module - add standard configuration modules

# LIBRARY

libcrypto, -lcrypto

# 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.
