"rsa->meth->rsa_sign" method in Openssl 1.1.1g

[prudvi raj]

While upgrading to openssl 1.1.1 from 1.0.2k .
I came across this code snippet :
    if (rsa->flags & RSA_FLAG_SIGN_VER)
        return rsa->meth->rsa_sign (type, m, lLen, sigret, siglen, rsa);

>From Docs :
Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign
and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions
will be called when RSA_sign() and RSA_verify() are used.
    /*
     * New sign and verify functions: some libraries don't allow arbitrary
     * data to be signed/verified: this allows them to be used. Note: for
     * this to work the RSA_public_decrypt() and RSA_private_encrypt()
should * *NOT* be used RSA_sign(), RSA_verify() should be used instead.
     */

 In Latest Openssl 1.1.1 :
-- RSA_FLAG_SIGN_VER is not required . To get flags : RSA_flags(rsa).
-- "struct rsa_meth_st" has  "rsa_sign" declared as a function pointer .  I
cannot find any actual function definition that the above "meth->rsa_sign "
might point to , which can be called as this forward declaration is not
allowed anymore . Maybe "RSA_sign()" ??

Moreover , "RSA_sign()" function has the same return code snippet above. .

So, what is a suitable replacement for the above snippet in openssl 1.1.1g
??

Can Someone help me on this !!, TIA .

Regards,
Prud.
