There are no method PEM_writeDSAPublicKey??

Hi!

I generated a DSA key pair and wrote the private key into a file, like following:

 DSA *pair = DSA_generate_parameters(1024, NULL, 0, NULL, NULL, NULL, NULL);
 DSA_generate_key(pair)
 EVP_PKEY *pkey = EVP_PKEY_new();
 EVP_PKEY_assign_DSA(pkey, pair);
 FILE *fp = fopen("dsaprivatekey.pem", "w");
 const EVP_CIPHER *c = EVP_des_ede3_cbc();
 string password = "abc123";
 int klen = password.length ();
 unsigned char *kstr = new unsigned char[klen];
 memcpy(kstr, password.c_str(), klen);
 PEM_write_PrivateKey(fp,pkey, c, kstr, klen, NULL, NULL); // writes the private key into a file
 fclose(fp);

Now I'd like to write the DSA public key into a file too, like the equivalent PEM_writeRSAPublicKey method does to RSA key pairs, but I didn't find any method to do this. There are some other method that does this to DSA keys? Or the solution is only via command line to generate a file with the public key?

Thanks for the help!
