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.
