NAME

6       DH_new, DH_free - allocate and free DH objects
7

SYNOPSIS

9        #include <openssl/dh.h>
10
11       The following functions have been deprecated since OpenSSL 3.0, and can
12       be hidden entirely by defining OPENSSL_API_COMPAT with a suitable
13       version value, see openssl_user_macros(7):
14
15        DH* DH_new(void);
16
17        void DH_free(DH *dh);
18

DESCRIPTION

20       DH_new() allocates and initializes a DH structure.
21
22       DH_free() frees the DH structure and its components. The values are
23       erased before the memory is returned to the system.  If dh is NULL
24       nothing is done.
25

RETURN VALUES

27       If the allocation fails, DH_new() returns NULL and sets an error code
28       that can be obtained by ERR_get_error(3). Otherwise it returns a
29       pointer to the newly allocated structure.
30
31       DH_free() returns no value.
32

HISTORY

38       All of these functions were deprecated in OpenSSL 3.0.
