Yes, the formats are incompatible. You need d2i_RSA_PUBKEY() instead.

But i think you have to free the memory using OPENSSSL_free().

Does the code look right?

3. How do I read or write a DER encoded buffer using the ASN1 functions?
...
The opposite assumes we already have len bytes in buf:
unsigned char *p;
p = buf;
p7 = d2i_PKCS7(NULL, &p, len);
At this point p7

What am I doing wrong here? I generate an RSA key. Then I DER encode
it. Then try to decode it, but the decode fails. The error says,

RSA* rsa = RSA_generate_key(2048, RSA_F4, 0, 0);

length is the length of the *pp data, that means it is the number of bytes that you
want to convert from DER to internal form, starting at location *pp.
