.SH NAME
OPENSSL_load_builtin_modules, ASN1_add_oid_module, ENGINE_add_conf_module \- add standard configuration modules
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 1
\& #include <openssl/conf.h>
\&
\& void OPENSSL_load_builtin_modules(void);
\& void ASN1_add_oid_module(void);
\& ENGINE_add_conf_module();
.Ve
.SH DESCRIPTION
.IX Header "DESCRIPTION"
The function \fBOPENSSL_load_builtin_modules()\fR adds all the standard OpenSSL
configuration modules to the internal list. They can then be used by the
OpenSSL configuration code.
.PP
\&\fBASN1_add_oid_module()\fR adds just the ASN1 OBJECT module.
.PP
\&\fBENGINE_add_conf_module()\fR adds just the ENGINE configuration module.
.SH NOTES
.IX Header "NOTES"
If the simple configuration function \fBOPENSSL_config()\fR is called then 
\&\fBOPENSSL_load_builtin_modules()\fR is called automatically.
.PP
Applications which use the configuration functions directly will need to
call \fBOPENSSL_load_builtin_modules()\fR themselves \fIbefore\fR any other 
configuration code.
.PP
Applications should call \fBOPENSSL_load_builtin_modules()\fR 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.
.SH "RETURN VALUE"
.IX Header "RETURN VALUE"
None of the functions return a value.
