OPENSSL_load_builtin_modules(3) LibreSSL OPENSSL_load_builtin_modules(3)

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.
