#include <openssl/dh.h>
int DH_size(DH *dh);
This function returns the Diffie-Hellman size in bytes. It can be used
to determine how much memory must be allocated for the shared secret
computed by DH_compute_key()
.
dh->p must not be NULL.
The size in bytes.

is available in all versions of SSLeay and OpenSSL.
