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 11 DH* DH_new(void); 12 13 void DH_free(DH *dh); 14 15=head1 DESCRIPTION 16 17DH_new() allocates and initializes a B<DH> structure. 18 19DH_free() frees the B<DH> structure and its components. The values are 20erased before the memory is returned to the system. 21If B<dh> is NULL nothing is done. 22 23=head1 RETURN VALUES 24 25If the allocation fails, DH_new() returns B<NULL> and sets an error 26code that can be obtained by L<ERR_get_error(3)>. Otherwise it returns 27a pointer to the newly allocated structure. 28 29DH_free() returns no value. 30 31=head1 SEE ALSO 32 33L<DH_new(3)>, L<ERR_get_error(3)>, 34L<DH_generate_parameters(3)>, 35L<DH_generate_key(3)> 36 37=head1 COPYRIGHT 38 39Copyright 2000-2016 The OpenSSL Project Authors.
