Been battling with this issue all day today, your video has saved me. Thank you!!

I have compiled your code many times, child always returns 1 on success and failure both. I wonder why ...

another problem i faced is the return status gets modulo by 256, so when you return 256 in this case it's actually like you returned 0 and it show "success" even thought "ping" is misspelled

so far I spent literally hours on your channel
not done yet
so next one goes now
your way of explaining really matches my ways of learning ;-)

But if you misspell the program name (pong instead of ping), you will get the "Could not find the program" message and also the "Success!" message, because the statusCode was 0 even though _execlp() could not find the program.

How to differentiate between the exit code 2 when received from the childprocess because ping was misspelled or the 2 that got returned from the ping program because the domain name was misspelled

Perhaps you will answer this question later in this series, but I am wondering how to see the exit code when I run main or some other binary from the command line. Especially when I compile and run with VS Code, the 0 from return 0 is not shown in the Terminal. Thanks!

there is a way to execute a command and get the stdout and the exit code?
i know i can get the output using popen(), but with this function i can't get the exit code
any suggestion, or something I can start from

I am newbie, so just curious, the wstatus is just an integer right? Can it have a different name or is it a part of some nomenclature to follow?

Hello, can you tell me how I can receive a value from the child process when it receives a signal?! To clarify, the parent sends a signal to the child, and the child should return a pontuatuion (int). Ty, love your videos!
