yes u can send signal from Intrrrupt context, as it sending signal just goes and set the signal bit in the proc structure. Basic Dont's are 1. Dont hold the interrupt context for long 2. Dont sleep in this context for any means 3. be sure of the locks and resources, you donot want to be waiting for a lock here or forever doing busy wait in a loop Anjaneyulu wrote: > > Hi, > I didn't send HTML mail.
