QUESTION
I have a problem figuring out how to use active child processes after they are created in the fork()
. I see from another terminal that they are still active until I execute the exit success. If I wanted to say for example: I want to make the child process with pid 10243, active at the moment, do this method. I would like to call the method after all the children have been initialized, so after the fork. Do I have to type execvp ()
?
execvp (methodName (a))
?
EDIT: I will try to add a similar code in order to be more specific
So let's say that I did a cycle where I create n child
...ANSWER
Answered 2021-Jun-12 at 09:57From the man page of fork:
The child process and the parent process run in separate memory spaces. At the time of fork() both memory spaces have the same content.
That means, all functions in the memory can be called by the parent and the child processes, but there is no way, that one process can call a function which resides in the memory space of another process.
For that you need IPC (Inter Process Communication).
Addendum:
After fork, you're able to run every function you like (in the child process - i hope you know what that means, if not, the provided link will help you out). But to 'make' a child process active and run a certain method is only possible via IPC.

I was trying to code Floyd's triangle in MIPS and for some reason, I cannot seem to figure out the problem but since my QTspim is crashing while I am running the code therefore I am guessing it is stuck in an infinite loop. I need help in getting out of the infinte loop. This is the part of code with the loops and everything :
...ANSWER
Answered 2021-Mar-31 at 15:51It seems like you are not incrementing the inner loop i.e. loop 2 anywhere and therefore its having issues and is getting stuck in an infinite loop. Apart from that it looks fine. Here is my code: main:

I've written a regex that matches all the function names in a string
...ANSWER
Answered 2021-Mar-17 at 13:28Following solution expects the pattern you provided (specifically spaces before and after function.)
The .match()
method provides an index
for the start position and use the .length
property of the string to get the end position:

Answered 2021-Feb-17 at 19:04you can look in google for "shallow equality" like here https://dmitripavlutin.com/how-to-compare-objects-in-javascript/#3-shallow-equality
this link as some cool way of doing it too https://www.samanthaming.com/tidbits/33-how-to-compare-2-objects/#es6-way-for-comparing-2-objects
but your solution is fine. if you would like an other way of writing it you can do

I am trying to do my first steps in reactive programming with Spring Boot (2.3.4.RELEASE). So far I am trying to creating an infinte stream of persons in a service method which is called in a REST controller method but it ends with that exception: "java.lang.IllegalStateException: The generator didn't call any of the SynchronousSink method " I tried to google some solutions for a few hours but I haven't found any propper one which fits to what I am trying to do.
This is my service method:

or a Flux
contain something called a sink
. The generator function, is the simplest form of generating a steady stream of items. The default sink is synchronous
and used for one-by-one
emissions, hence synchronousSink
.
So by calling the generator method you expose the inner sink, and you need to feed items through the sink api by calling the sinks functions next
, complete

I'm in the process of coding the knight's tour function, and I'm as far as this where I'm getting an infinte loop in my ghci:
...ANSWER
Answered 2020-Dec-21 at 00:24I think one of the main problems is checking if you have visited a square. This takes too much time. You should look for a data structure that makes that more efficient.
For small boards, for example up to 8×8, you can make use of a 64-bit integer for that. A 64-bit can be seen as 64 booleans that each can represent whether the knight already has visited that place.
we thus can implement this with:
