=head1 DESCRIPTION
DSA_SIG_free() frees the B<DSA_SIG> structure and its components. The
values are erased before the memory is returned to the system.
+DSA_SIG_get0() returns internal pointers to the B<r> and B<s> values contained
+in B<sig>.
+
+The B<r> and B<s> values can be set by calling DSA_SIG_set0() and passing the
+new values for B<r> and B<s> as parameters to the function. Calling this
+function transfers the memory management of the values to the DSA_SIG object,
+and therefore the values that have been passed in should not be freed directly
+after this function has been called.
+
=head1 RETURN VALUES
If the allocation fails, DSA_SIG_new() returns B<NULL> and sets an
DSA_SIG_free() returns no value.
+DSA_SIG_set0() returns 1 on success or 0 on failure.
