from what i've read, the empty function sorta checks if any processes are running. but it's kinda complicated, because u have 2 set variables in each process 2 relate 2 the condition variable, then u have 2 use the wait command b4 u use empty putting return in a process will end it, and it works in if statements. it's prolly the way u want 2 go |

he isnt we were having that trouble with it too because we wanted teh process to end just as a proc ended so we looked up empty well u need a boolean and i guess when its true it doesnt tell the process to end when its false the empty ends the thing |

well i don't feel like trying but i remember a while back when hello and i were working on our game i tried using empty. apparently, a condition variable ISN'T a boolean variable. I tried constant variables too, but no go. or it could be, and i'm just an idiot. hope not. neways try the tutorials, someone might've tried posting something about the whole wait, empty, signal commands. |
