1=pod 2 3=head1 NAME 4 5OPENSSL_load_builtin_modules, ASN1_add_oid_module, ENGINE_add_conf_module - add standard configuration modules 6 7=head1 SYNOPSIS 8 9 #include <openssl/conf.h> 10 11 void OPENSSL_load_builtin_modules(void); 12 void ASN1_add_oid_module(void); 13 void ENGINE_add_conf_module(void); 14 15=head1 DESCRIPTION 16 17The function OPENSSL_load_builtin_modules() adds all the standard OpenSSL 18configuration modules to the internal list. They can then be used by the 19OpenSSL configuration code. 20 21ASN1_add_oid_module() adds just the ASN1 OBJECT module. 22 23ENGINE_add_conf_module() adds just the ENGINE configuration module. 24 25=head1 NOTES 26 27If the simple configuration function OPENSSL_config() is called then 28OPENSSL_load_builtin_modules() is called automatically. 29 30Applications which use the configuration functions directly will need to 31call OPENSSL_load_builtin_modules() themselves I<before> any other 32configuration code. 33 34Applications should call OPENSSL_load_builtin_modules() to load all 35configuration modules instead of adding modules selectively: otherwise 36functionality may be missing from the application if an when new 37modules are added. 38 39=head1 RETURN VALUES 40 41None of the functions return a value. 42 43=head1 SEE ALSO 44 45L<config(5)>, L<OPENSSL_config(3)> 46 47=head1 HISTORY 48 49ENGINE_add_conf_module() was deprecated in OpenSSL 3.0. 50 51=head1 COPYRIGHT 52 53Copyright 2004-2020 The OpenSSL Project Authors.
