I want to invoke from a thread an alarm in main ,How will I achieve that,

You cannot. Any signal raised within your thread will only be seen by that thread; not main.

This will depend on what precisely you mean by "message", but consider sockets or shared variables or signals as some things to investigate first. Perhaps see perlipc for starters.	[reply]
