< 1596316530 817654 :zzo38!~zzo38@host-24-207-14-22.public.eastlink.ca PRIVMSG #esoteric :Yes, it is what I think my "cfork" would be better. For compatibility with other programs, you can also define the macro:   #define fork() (cfork()?:detach())

< 1596317549 751666 :b_jonas!~x@catv-176-63-12-45.catv.broadband.hu PRIVMSG #esoteric :you can just write normal code
< 1596317741 503713 :zzo38!~zzo38@host-24-207-14-22.public.eastlink.ca PRIVMSG #esoteric :Yes, if you fork, then you can check the error normally. However, the normal fork() function it is a bit difficult for the parent to detect errors in the child process, I think. So, fork is good, and for some purposes, cfork is a better alternative.
< 1596317748 627031 :shachaf!~shachaf@unaffiliated/shachaf PRIVMSG #esoteric :I don't follow.
< 1596317772 431347 :shachaf!~shachaf@unaffiliated/shachaf PRIVMSG #esoteric :Anyway, there are many options. posix_spawn lets you specify open/close/dup2 actions and doesn't even let you check for errors.

< 1596317883 18030 :b_jonas!~x@catv-176-63-12-45.catv.broadband.hu PRIVMSG #esoteric :zzo38: posix_spawn is a windows thing, a crutch because they don't have a real fork, but gives a sort-of unix-like interface rather than a winapi interface
< 1596317890 273232 :shachaf!~shachaf@unaffiliated/shachaf PRIVMSG #esoteric :It is not a system call, just a POSIX API for running programs.
< 1596317891 845196 :b_jonas!~x@catv-176-63-12-45.catv.broadband.hu PRIVMSG #esoteric :(actually it also exists on linux)
< 1596317934 661014 :shachaf!~shachaf@unaffiliated/shachaf PRIVMSG #esoteric :posix_spawn is a Windows thing? I am skeptical.
< 1596317983 51971 :shachaf!~shachaf@unaffiliated/shachaf PRIVMSG #esoteric :Windows implemented fork in the kernel for WSL1.

< 1596318107 951045 :zzo38!~zzo38@host-24-207-14-22.public.eastlink.ca PRIVMSG #esoteric :Well cfork would be a bit like vfork, but improved; it returns either 0 to the child process, or -1 to the parent process in case it can't fork (it won't do both), and then exec or detach or _exit will return to the parent process (detach returns to both the child and parent process; exec and _exit return only to the parent process). Until the parent process resumes, the memory, registers, stack, etc are shared.
< 1596318120 474384 :zzo38!~zzo38@host-24-207-14-22.public.eastlink.ca PRIVMSG #esoteric :That is what it is. Can it be understand now?
< 1596318155 845513 :shachaf!~shachaf@unaffiliated/shachaf PRIVMSG #esoteric :What is the benefit of allowing detach?
< 1596318159 949862 :zzo38!~zzo38@host-24-207-14-22.public.eastlink.ca PRIVMSG #esoteric :(You can then also see why fork() is the same as (cfork()?:detach()); this also explains the return value of detach(). I can also provide other example if wanted.)
< 1596318165 156739 :shachaf!~shachaf@unaffiliated/shachaf PRIVMSG #esoteric :It seems like it'd make the implementation a good deal more complicated.
< 1596318302 553800 :zzo38!~zzo38@host-24-207-14-22.public.eastlink.ca PRIVMSG #esoteric :Well, since some programs may use fork(), and in some cases it is more useful than cfork(), too; maybe you might also want to change other things before detaching (or to more easily report some things from initialization to the parent before detaching).
< 1596318335 855468 :zzo38!~zzo38@host-24-207-14-22.public.eastlink.ca PRIVMSG #esoteric :So, that is why, instead of a fork() system call, it is just implemented as (cfork()?:detach()) instead.
