OPENSSL_load_builtin_modules - add standard configuration modules

<H1><A NAME="SYNOPSIS">SYNOPSIS</A></H1>
<PRE> #include &lt;openssl/conf.h&gt;

<H1><A NAME="DESCRIPTION">DESCRIPTION</A></H1>
<P>
The function <CODE>OPENSSL_load_builtin_modules()</CODE> adds all the
standard OpenSSL configuration modules to the internal list. They can then
be used by the OpenSSL configuration code.

</P>
<P>
<CODE>ASN1_add_oid_module()</CODE> adds just the ASN1 OBJECT module.

</P>
<P>
<CODE>ENGINE_add_conf_module()</CODE> adds just the ENGINE configuration
module.

</P>
<P>
<HR>
<H1><A NAME="NOTES">NOTES</A></H1>
<P>
If the simple configuration function <CODE>OPENSSL_config()</CODE> is
called then <CODE>OPENSSL_load_builtin_modules()</CODE> is called
automatically.

</P>
<P>
Applications which use the configuration functions directly will need to
call <CODE>OPENSSL_load_builtin_modules()</CODE> themselves <EM>before</EM> any other configuration code.

</P>
<P>
Applications should call <CODE>OPENSSL_load_builtin_modules()</CODE> 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.

<HR>

<P>
None of the functions return a value.
