 cause of grief here are some code fragments using PKCS7 as an example:

 At this point buf contains the len bytes of the DER encoding of
 p7.
 
 The opposite assumes we already have len bytes in buf:

 occurred. If an error occurred ERR_print_errors(bio) should give more

 Memory allocation and encoding can also be combined in a single
 operation by the ASN1 routines:
 
- unsigned char *buf = NULL;	/* mandatory */
- int len;
- len = i2d_PKCS7(p7, &buf);
- if (len < 0)

  /* Do some things with 'buf' */
  /* Finished with buf: free it */

 In this special case the "buf" parameter is *not* incremented, it points
 to the start of the encoding.
