Member Function Documentation

◆ signal()

long L4Re::Parent::signal ( unsigned long  sig,
unsigned long  val 
)

Send a signal to the parent.

Parameters
sigSignal to send
valValue of the signal
Return values
0Success
<0IPC error
Note
The implementations of this interface in Moe and Ned only recognize the signal 0, in which case they will terminate the application from which the interface was invoked and not return. In this case, val is treated as the application's return code. For any other value of sig, the method just returns successfully.
