DH_new(3)

     NAME
          DH_new, DH_free - allocate and free DH objects

     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.

     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.
