DH_new(3)                           OpenSSL                          DH_new(3)



NAME
       DH_new, DH_free - allocate and free DH objects

LIBRARY
       libcrypto, -lcrypto

SYNOPSIS
        #include <openssl/dh.h>

        DH* DH_new(void);

        void DH_free(DH *dh);

DESCRIPTION
       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.

RETURN VALUES
       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.
