     NAME
          DH_size - get Diffie-Hellman prime size

     SYNOPSIS
           #include <openssl/dh.h>

           int DH_size(DH *dh);

     DESCRIPTION
          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.

     RETURN VALUE
          The size in bytes.

     SEE ALSO
          dh(3), DH_generate_key(3)

     HISTORY
          DH_size() is available in all versions of SSLeay and
          OpenSSL.
