+=head1 NAME
+
+X509_REQ_get_extensions,
+X509_REQ_add_extensions, X509_REQ_add_extensions_nid
+- handle X.509 extension attributes of a CSR
+
+=head1 SYNOPSIS
+
+ #include <openssl/x509.h>
+
+ STACK_OF(X509_EXTENSION) *X509_REQ_get_extensions(X509_REQ *req);
+ int X509_REQ_add_extensions(X509_REQ *req, const STACK_OF(X509_EXTENSION) *exts);
+ int X509_REQ_add_extensions_nid(X509_REQ *req,
+                                 const STACK_OF(X509_EXTENSION) *exts, int nid);
+
+=head1 DESCRIPTION
+
+X509_REQ_get_extensions() returns the first list of X.509 extensions
+found in the attributes of I<req>.
+The returned list is empty if there are no such extensions in I<req>.
+The caller is responsible for freeing the list obtained.
+
+X509_REQ_add_extensions() adds to I<req> a list of X.509 extensions I<exts>,
+which must not be NULL, using the default B<NID_ext_req>.
+This function must not be called more than once on the same I<req>.
+
+X509_REQ_add_extensions_nid() is like X509_REQ_add_extensions()
+except that I<nid> is used to identify the extensions attribute.
+This function must not be called more than once with the same I<req> and I<nid>.
+
+=head1 RETURN VALUES
+
+X509_REQ_get_extensions() returns a pointer to B<STACK_OF(X509_EXTENSION)>
+or NULL on error.
+
+X509_REQ_add_extensions() and X509_REQ_add_extensions_nid()
+return 1 on success, 0 on error.
