thoth	And poll is so much simpler and cleaner uwu and select's man page even recommends to use it. One hassle less.	15:02:18
thoth	Sometimes more complex != more performance :)	15:02:54
thoth	Thanks tthom, we can chat again maybe after I read the article you linked? You were such a help and a encouragement and made me feel so good uwu	15:13:09
tthom	No probs	15:49:32
thoth	In reply to @tthom:ahtoms.xyz Data is sent to those file descriptors, events like POLLIN are watched by poll to see if data had been written to that file which the file descriptor maps to. When it stops waiting, it isn't that it knows what exact file descriptor got the data but it knows at least one in the set of file descriptors it is watching received a signal Hmm where would I have the POLL things then? Because by how we talked - I planned on having POLL on each thread, but if every thread check if the file descriptor of the next POLL's incoming data is the one the current thread is working for, then that'll be like x30 of something energy waste..	16:33:31
thoth	I might have poll and accept in the main aka producer thread.	16:33:46
thoth	Opinions, worries, questions?	16:33:58
tthom	You could simply just attempt to do poll on a single thread and compare your results with your multi-threaded application, if you are going to use poll with multiple threads, you could have a set number of connections a single thread manages.	16:35:00
thoth	I do - 1 xD	16:38:00
thoth	Or did you mean yet another thread, for poll-managing?	16:38:27
thoth	That might be ideal.. Have 1 main thread aka producer - accept connections Have say 1 thread aka police-men - forward poll-incoming and outgoing traffic to other threads Other threads - handle the incoming/outgoing traffic	16:40:02
thoth	* That might be ideal.. Have 1 main thread aka producer - accept connections Have say 1 thread aka police-men - forward poll-incoming and outgoing traffic to other threads Other threads - handle the incoming/outgoing traffic	16:40:04
thoth	In reply to @thoth:cuum.space Or did you mean yet another thread, for poll-managing? As to not slow down any incoming clients	16:43:25
tthom	Just one thread (main) is required with poll, just set up an array with the number of file descriptors you want to handle and have a loop where it will detect the event, find the file descriptor it occurred on and you have a function that operates on it. Do note, you would likely want to set handling of these files to non-blocking as well	17:11:39
thoth	Yeah, it shouldn't be that slow xD	17:20:50
thoth	In reply to @thoth:cuum.space That might be ideal.. Have 1 main thread aka producer - accept connections Have say 1 thread aka police-men - forward poll-incoming and outgoing traffic to other threads Other threads - handle the incoming/outgoing traffic This would only add complexity	17:21:04

Do note, you would likely want to set handling of these files to non-blocking as well You mean the timeout parameter in poll?	17:21:53
tthom	From memory you can set it to -1 and it holds until a signal is generated	17:23:17
tthom	If you want it to do work when there is no activity, then give it a timeout that you think is reasonable	17:25:00
thoth	In reply to @tthom:ahtoms.xyz From memory you can set it to -1 and it holds until a signal is generated I know, that's the blocking, and yuo said to set it to non-blocking lol What you probably meant is set it to 1?	17:26:05
thoth	Because I might want to do stuff even if there's nothing to receive?	17:26:23
tthom	non-blocking is meant to be described to the file descriptor	17:26:24
thoth	or I might just be dumb IDK I'll figure it out	17:26:30
tthom	By default, all reads are blocking	17:26:34
thoth	In reply to @tthom:ahtoms.xyz If you want it to do work when there is no activity, then give it a timeout that you think is reasonable That's what I meant sorry	17:26:54
thoth	Didn't read on time	17:26:57
thoth	In reply to @tthom:ahtoms.xyz By default, all reads are blocking I know man, I read some shit :D proud badge show-off	17:27:17
tthom	So say like you go read(fd, buf, 256); It will wait until there is data there. You want to call fcntl with O_NONBLOCK flag (probably want to do this twice so you get the bits and the second time to get the bits with new bit set to say it should be non-blocking).	17:28:49
thoth	I am confused with the last part	18:32:50
thoth	But I did see fcntl and O_NONBLOCK things in some code and in man pages	18:33:10
