15:53 There is nothing with RDI register, just (in Linux) the exit codes are specified in the range 0-255 (1 byte). The number 420 lost its most significant bytes and became 164.

`man 3 exit` states: "The exit() function causes normal process termination and the least significant byte of status (i.e., status & 0xFF) is returned to the parent." Turns out `420 & 0xFF == 164`.

I really appreciate that the sequences, where you are not quite sure are NOT cut out. It's really helpful, to see the thought process in a specific language / context, when you are not sure what to do. For example, which docs to turn to, or how to use intellisense etc. to find the information one needs to solve the problem. Seeing just some finished code explained is not nearly as helpful as this format in my opinion. Very watchable. Thank you!

Feels really genuine that you dont know everything and use Google, really shows how the day to day of a software engineer is.

No cap, how do I donate? Never even considered donating to a UKpostsr before but this, but this is the content that’s enjoyable. Not the average hour long video with cuts and edits everywhere, because every time the person has to look something up it’s all secretive and never seen. I got a lot of respect for someone that is probably a little bit nervous because they may be using a language they’re not be 110% comfortable or familiar with, but is well and truly comfortable enough to show what’s going on in their head as they walk through the project and show all the pivots and everything that’s happening. I fucking love it, I got a lot of respect for it and I want to support this kind of “free thought with a goal” style UKposts videos. If you’ve got some way to accept donations, let me know 🙌💪

The exit code returned by the kernel is taken modulo 256, so you'll get the remainder when 420 is divided by 256, which is 164.
@SimGunther

Technically the assembler knows the size of each register, so it would just take the 8 bits necessary for the machine code, no modulus needed :)

@victorshilin9360 8 місяців тому
The important difference is that the value 420 is never truncated by the assembler itself, nor the limitation of the rdi register. The 64-bit value gets passed as is to the kernel, and the exit code is indeed taken by modulo 256.
