(...) Shouldn't (...) No, the returned process id is an integer (int) I believe, you just replace it with int pid1 = execi .... for example :) - Ciaran (24 years ago, 13-Mar-01, to lugnet.robotics.rcx.legos)

It probably should. But why does it say that "pid1" is undeclared? Shouldn't that be taken care of in tm.h or unistd.h? (24 years ago, 13-Mar-01, to lugnet.robotics.rcx.legos)

Hi, I have been poking around in the legOS kernel and it appears that there is no formal way to pass messages between tasks - only shared protected resources through semaphores. I intend to modify the kernel to add the features descried below. Note (...) (24 years ago, 13-Mar-01, to lugnet.robotics.rcx.legos)

I worked on that. I'm having trouble with "execi()" and some stuff related to it. Here's the offending area, but not the entire program: int main(int argc, char **argv) { pid1=execi(&startup, 0, NULL, 1, DEFAULT_STACK_SIZE); MYexit = -1; cputs("x"); (...)

(...) No, it will not. Functions don't work like that, in general. If you want to call a function and have it run independently of the calling function, you must use execi() to start it. (24 years ago, 12-Mar-01, to lugnet.robotics.rcx.legos)

Thanks for the response! Now I'm almost ready to test it. I just need to know if, when you have a call void function, and you then use the int main() to close the program with return 0;, will the void keep running? Here's my current copy, without (...)

(...) I think you mean if (enemy == 1). Also, the identifier "fight" resolves to the address of the fight function. Doing "fight;" is equivalent to doing "1;". It's legal, but it doesn't accomplish anything. You want to do "fight();" and (...) (24 years ago, 12-Mar-01, to lugnet.robotics.rcx.legos)

I'm building a video game type thing. It has three touch sensors, for left, right, and fire. The LCD controls where the enemy is. I'm having some problems with my code, so here it is(I'm using kernel 0.2.4): #include "conio.h" #include "dmotor.h" (...) (24 years ago, 12-Mar-01, to lugnet.robotics.rcx.legos)
