11 DSA* DSA_new(void);

13 void DSA_free(DSA *dsa);

15=head1 DESCRIPTION
16
17DSA_new() allocates and initializes a B<DSA> structure. It is equivalent to
18calling DSA_new_method(NULL).
19
20DSA_free() frees the B<DSA> structure and its components. The values are
21erased before the memory is returned to the system.
22
23=head1 RETURN VALUES
24
25If the allocation fails, DSA_new() returns B<NULL> and sets an error
26code that can be obtained by
27L<ERR_get_error(3)|ERR_get_error(3)>. Otherwise it returns a pointer
28to the newly allocated structure.
29
30DSA_free() returns no value.
