1=pod 2 3=head1 NAME 4 5DH_new, DH_free - allocate and free DH objects 6 7=head1 SYNOPSIS 8 9 #include <openssl/dh.h> 10 11The following functions have been deprecated since OpenSSL 3.0, and can be 12hidden entirely by defining B<OPENSSL_API_COMPAT> with a suitable version value, 13see L<openssl_user_macros(7)>: 14 15 DH* DH_new(void); 16 17 void DH_free(DH *dh); 18 19=head1 DESCRIPTION 20 21DH_new() allocates and initializes a B<DH> structure. 22 23DH_free() frees the B<DH> structure and its components. The values are 24erased before the memory is returned to the system. 25If B<dh> is NULL nothing is done. 26 27=head1 RETURN VALUES 28 29If the allocation fails, DH_new() returns B<NULL> and sets an error 30code that can be obtained by L<ERR_get_error(3)>. Otherwise it returns 31a pointer to the newly allocated structure. 32 33DH_free() returns no value. 34 35=head1 SEE ALSO 36 37L<DH_new(3)>, L<ERR_get_error(3)>, 38L<DH_generate_parameters(3)>, 39L<DH_generate_key(3)>, 40L<EVP_PKEY-DH(7)> 41 42=head1 HISTORY 43 44All of these functions were deprecated in OpenSSL 3.0. 45 46For replacement see EVP_PKEY-DH(7). 47 48=head1 COPYRIGHT 49 50Copyright 2000-2016 The OpenSSL Project Authors.
