+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+\&\fBX509_REQ_get_extensions()\fR returns the first list of X.509 extensions
+found in the attributes of \fIreq\fR.
+The returned list is empty if there are no such extensions in \fIreq\fR.
+The caller is responsible for freeing the list obtained.
+.PP
+\&\fBX509_REQ_add_extensions_nid()\fR adds to \fIreq\fR a list of X.509 extensions \fIexts\fR,
+using \fInid\fR to identify the extensions attribute.
+\&\fIreq\fR is unchanged if \fIexts\fR is NULL or an empty list.
+This function may be called more than once on the same \fIreq\fR and \fInid\fR.
+In such case any previous extensions are augmented, where an extension to be
+added that has the same OID as a pre-existing one replaces this earlier one.
+.PP
+\&\fBX509_REQ_add_extensions()\fR is like \fBX509_REQ_add_extensions_nid()\fR
+except that the default \fBNID_ext_req\fR is used.
+.SH "RETURN VALUES"
+.IX Header "RETURN VALUES"
+\&\fBX509_REQ_get_extensions()\fR returns a pointer to \fBSTACK_OF(X509_EXTENSION)\fR
+or NULL on error.
+.PP
+\&\fBX509_REQ_add_extensions()\fR and \fBX509_REQ_add_extensions_nid()\fR
+return 1 on success, 0 on error.
