OPENSSL_load_builtin_modules(3)

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);
 void ENGINE_add_conf_module(void);

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 VALUES
None of the functions return a value.
