DH_new, DH_free - allocate and free DH objects
#include <openssl/dh.h>
DH* DH_new(void);
void DH_free(DH *dh);
DH_new() allocates and initializes a DH structure.
DH_free() frees the DH structure and its components. The values are
erased before the memory is returned to the system.
If the allocation fails, DH_new() returns NULL and sets an error
code that can be obtained by ERR_get_error. Otherwise it returns
a pointer to the newly allocated structure.
DH_free() returns no value.

DH_new() and DH_free() are available in all versions of SSLeay and OpenSSL.
