Thevalues are erased before the memory is returned to the system.=head1 RETURN VALUESIf the allocation fails, DSA_SIG_new() returns B<NULL> and sets anerror code that can be obtained byL<ERR_get_error(3)|ERR_get_error(3)>. Otherwise it returns a pointerto the newly allocated structure.DSA_SIG_free() returns no value.=head1 SEE ALSOL<dsa(3)|dsa(3)>, L<err(3)|err(3)>, L<DSA_do_sign(3)|DSA_do_sign(3)>=head1 HISTORYDSA_SIG_new() and DSA_SIG_free() were added in OpenSSL 0.9.3.=cut
