=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
|
2000-01-27 09:25:31 +08:00
|
|
|
code that can be obtained by L<ERR_get_error(3)|ERR_get_error(3)>. Otherwise it returns
|
2000-01-23 04:05:23 +08:00
|
|
|
a pointer to the newly allocated structure.
|
|
|
|
|
|
|
|
|
|
DH_free() returns no value.
