Hello, You can find attached the patch that adds into librt optional support for stubs of the aio functions, as I promised a few days ago.
It's mostly a copy/paste from glibc, with a few modifications needed for it to compile, I hope I haven't missed anything and that there won't be license-related issues. Best regards, Cristi -- Ing. Cristi Măgherușan, Universitatea Tehnică din Cluj-Napoca Centrul de Comunicații "Pusztai Kalman" Tel. 0264/401247 http://cc.utcluj.ro
