=pod =head1 NAME DH_new, DH_free - allocate and free DH objects =head1 SYNOPSIS #include <openssl/dh.h> DH* DH_new(void); void DH_free(DH *dh); =head1 DESCRIPTION DH_new() allocates and initializes a B<DH> structure. DH_free() frees the B<DH> structure and its components. The values are erased before the memory is returned to the system. If B<dh> is NULL nothing is done. =head1 RETURN VALUES If the allocation fails, DH_new() returns B<NULL> and sets an error code that can be obtained by L<ERR_get_error(3)>. Otherwise it returns a pointer to the newly allocated structure. DH_free() returns no value. =head1 SEE ALSO L<DH_new(3)>, L<ERR_get_error(3)>, L<DH_generate_parameters(3)>, L<DH_generate_key(3)> =head1 COPYRIGHT Copyright 2000-2016 The OpenSSL Project Authors.
