Father-son process in which the process may receive a variable value I would like to monitor the process through the father son operation of the process, would like to have the process variable values son How sub-processes operating together I would like to do a monitoring process procedures father Father-son process in which the process may receive a variable value Inter-Process Communication with bars, such as shared memory and so on, if only to see whether the process son alive, could signal. Father-son process in which the process may receive a variable value I just want to look inside the process of the value son Specifically how to achieve that where such examples (and I find a lot of places, failed to find) Thank you Father-son process in which the process may receive a variable value If the process is to see Lane, son of variable value, it needs explicit process son to "share" out to others, it can be used or shared memory mmap, of the specific approach, there is the essence of the C version of the relevant documents. Father-son process in which the process may receive a variable value I played a number of sub-processes With a sub-process procedures How it should run Father-son process in which the process may receive a variable value Process and the process is one thing more than two are inter-process communication.
