.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This function processes any X509v3 extensions that might be present in an X509
object and caches the result of that processing. Many OpenSSL functions that use
an X509 object will cause extensions to be processed and cached implicitly. If
this is done implicitly then the default library context and property query
string will be used. In some cases it may be desirable to use some other library
context and property query string. If so then an application can call
\&\fBX509v3_cache_extensions()\fR explicitly. This should be done before any function
that needs to use those extensions is called \- otherwise calling
\&\fBX509v3_cache_extensions()\fR will have no effect. Typically this means calling this
soon after creation of the X509 object. The X509 object to be processed is
given in \fIx\fR and the library context and property query string to use are given
in \fIlibctx\fR and \fIpropq\fR.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
This function returns 0 if the extensions are invalid or an error occurred.
Otherwise it returns 1.
