Below is an explanation of detach and join in threads.<\/p>\n\n\n\n

The detach method completely separates thread operations from the background.<\/p>\n\n\n\n

Because they are completely separated and operate independently, it is difficult to know the termination point and difficult to control.<\/p>\n\n\n\n

It is used for relatively simple tasks.<\/p>\n\n\n\n
\u2714\ufe0f join<\/p>\n\n\n\n
— join()\uc740 joinable()\uc774 true\uc774\uba74 \uc2a4\ub808\ub4dc\ub97c \ub300\uae30\uc0c1\ud0dc\ub85c \ub9cc\ub4dc\ub294 \ud568\uc218\uc785\ub2c8\ub2e4.
join() is a function that puts a thread into a waiting state if joinable() is true.<\/p>\n\n\n\n
— join\uc744 \uc0ac\uc6a9\ud558\ub294 \ubc29\uc2dd\uc740 \uc2a4\ub808\ub4dc\uc758 \uc885\ub8cc\uc9c0\uc810\uc744 \uad00\ub9ac \uac00\ub2a5\ud558\uae30\ub54c\ubb38\uc5d0 \ubcf5\uc7a1\ud55c \uc11c\ubc84\ub098 \ub300\uaddc\ubaa8 \ud504\ub85c\uadf8\ub7a8\uc5d0\uc11c \uc0ac\uc6a9\ub429\ub2c8\ub2e4.
The join method is used in complex servers or large-scale programs because it allows for the management of thread termination points.<\/p>\n\n\n\n
