Please help me out for the below problem. Am new to this forum.
One program(let it be server) will poll the database and update the shared memory. So whenever there is new data available in the shared memory, it has to send signal to the other program(let it be client, this may be in the same machine or diferent machine), then the client will read the data from that shared memory.
I want to know how to send a signal from the server to the client. I need to send from one program to another porgram. The client program may started up later at any time after the start of server. So tell me how to send the signal from server to client whenever the shared memory is updated.
Thanks & Regards,
