Format with three backticks followed by the letter c and a newline, then your code, then finally three backticks

#

No spaces between the first three backticks and c

# 
/* If you're on the desktop Discord
 * client this should be nicely colored
 */
int main(void) {
    return 0;
}```
#

Backticks, not backslashes

#

Like an apostrophe but kind of tilted backwards a bit

#

Nice, yes

#

That looks like it would work

3 backticks: ```

Also a blood sucking insect that attaches to your back and transmits diseases

#

I assume

#

There was just a memmove, no looping in the code you pasted

#

And btw paste a full example that compiles if you want help and use globals etc. mystery variables and functions

#

Explaining it like that is useless because the code itself is the only thing that can show what is happening

#

You aren't the judge of what's helpful, it's not possible to reason about code that isn't visible

#

The memmove moves the array one entry so that previous index 1 becomes 0, etc, so the first pid is indeed overwritten, and so are all the rest

#

If that's not enough you have to provide more detail

#

I said explanations are not a replacement for reading the code

#

The basic thing is: you need help with C syntax and/or code. For you to be able to explain the problem in sufficient detail you would need to understand it all well enough to not need to ask.

#

You can't get a car problem diagnosed as a non-mechanic by explaining your impression of your car troubles to the mechanic. He/she needs to look at the actual thing to find out.

Looks like uninitialized memory maybe

#

Are you updating all the pointers you use to refer to the array? Realloc can change the address.

#

Again not enough code for me to know
