DH_new, DH_free - allocate and free DH objects
#include <openssl/dh.h>
The following functions have been deprecated since OpenSSL 3.0, and can be
hidden entirely by defining
OPENSSL_API_COMPAT with a suitable version
value, see
openssl_user_macros(7):
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
dh is NULL
nothing is done.
If the allocation fails,
DH_new() returns
NULL and sets an error
code that can be obtained by
ERR_get_error(3). Otherwise it returns a
pointer to the newly allocated structure.
DH_free() returns no value.

ERR_get_error(3),
DH_generate_parameters(3),

All of these functions were deprecated in OpenSSL 3.0.
For replacement see
EVP_PKEY-DH(7).
