Generate symmetric key DES3

[Angel Martinez Gonzalez]

Hello:

I want to generate a symmetric key with DES. But I donīt know very well, how
do it.

I tried the following:

void GenerateKey()
{
  DES_cblock *ret ;

  RAND_screen();

  printf("Staus of PRNG: %i\n",RAND_status());

 DES_random_key(ret);

 printf("key: %i\n",ret);
}

But I obtained an error of execution. What I do wrong?. How I can generate a
DES symmetric key?.

Thanks.
