NAME

       X509_REQ_get_extensions, X509_REQ_add_extensions, X509_REQ_add_extensions_nid - handle
       X.509 extension attributes of a CSR

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);

DESCRIPTION

       X509_REQ_get_extensions() returns the first list of X.509 extensions found in the
       attributes of req.  The returned list is empty if there are no such extensions in req.
       The caller is responsible for freeing the list obtained.

       X509_REQ_add_extensions() adds to req a list of X.509 extensions exts, which must not be
       NULL, using the default NID_ext_req.  This function must not be called more than once on
       the same req.

       X509_REQ_add_extensions_nid() is like X509_REQ_add_extensions() except that nid is used to
       identify the extensions attribute.  This function must not be called more than once with
       the same req and nid.

RETURN VALUES

       X509_REQ_get_extensions() returns a pointer to 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.
