|  | =head1 NAME | 
|  |  | 
|  | OPENSSL_load_builtin_modules, ASN1_add_oid_module, ENGINE_add_conf_module - add standard configuration modules | 
|  |  | 
|  | =head1 SYNOPSIS | 
|  |  | 
|  | #include <openssl/conf.h> | 
|  |  | 
|  | void OPENSSL_load_builtin_modules(void); | 
|  | void ASN1_add_oid_module(void); | 
|  | ENGINE_add_conf_module(); | 
|  |  | 
|  | =head1 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. | 
|  |  | 
|  | =head1 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 I<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. | 
|  |  | 
|  | =head1 RETURN VALUE | 
|  |  | 
|  | None of the functions return a value. |
