Share events between process
« on: December 11, 2020, 04:25:58 PM »
I'm working on a LCD client program that connects to lcdproc server and shows some music information on my network.
I made a second program, an simple blinking led using gpio and wiringPi lib that i want to use until LCD client is ready.
On Raspberry startup, the LED program starts first, so i would like to know what is the best and simplest way for LED program to check when LCD client is
 ready. LCD client will not ends and do some internal works on startup, so wait the process to stops is not possible.
So i would like the LCD client "informs" LED program that it's ready.

Any suggestion will be appreciathed!
Thank you,
