Migrating OpenSSL to 1.1.1

[DOpenssl]

I am migrating OpenSSL to 1.1.1, I am getting error for below macros:

M_ASN1_D2I_vars(a, X509_CRL *, X509_CRL_new)
M_ASN1_D2I_Init()
M_ASN1_D2I_start_sequence()
M_ASN1_D2I_get(ret->crl, d2i_X509_CRL_INFO)
M_ASN1_D2I_get(ret->sig_alg, d2i_X509_ALGOR)
M_ASN1_D2I_get(ret->signature, d2i_ASN1_BIT_STRING)
M_ASN1_D2I_Finish(a, X509_CRL_free, ASN1_F_X509_CRL_ADD0_REVOKED);

Can anyone help me to identify alternative macros/functions in openssl1.1.1 for this one?

This looks like its just reading the DER for an X509_CRL object. The equivalent would be calling d2i_X509_CRL:

Thanks for your answer...

Do you have any example for this one? OR
Any code reference where we are reading the DER for an X509_CRL object?

There's an example of this function being used to read DER data in the test suite:

openssl/test/x509_test.c

Lines 103 to 115 in 53a8728

	static int test_x509_crl_tbs_cache(void)
	{
	int ret;
	X509_CRL *crl = NULL;
	const unsigned char *p = crldata;
	ret = TEST_ptr(crl = d2i_X509_CRL(NULL, &p, sizeof(crldata)))
	&& TEST_int_gt(X509_CRL_sign(crl, privkey, signmd), 0)
	&& TEST_int_eq(X509_CRL_verify(crl, pubkey), 1);
	X509_CRL_free(crl);
	return ret;
	}
