7=head1 SYNOPSIS

10
11 DSA* DSA_new(void);
12
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.
22If B<dsa> is NULL nothing is done.
23
24=head1 RETURN VALUES
25
26If the allocation fails, DSA_new() returns B<NULL> and sets an error
27code that can be obtained by
28L<ERR_get_error(3)>. Otherwise it returns a pointer
29to the newly allocated structure.
30
31DSA_free() returns no value.
