signal & slow devices

[Christophe Wolfhugel]

System V manual indicate that an operation, like read, write on a slow
device (is a parralel port considered as slow?) may be interrupted and
return -1 upond receipt of a caught signal.

In the cas of a write, can I be sure that in case I get a -1 return code
*none* of the buffer has been sent to the device.?
