Hello everyone! :-D
OK, I'm making a game, and I need the enemies to move on a separate thread. I know how to do threads in C#, but not on C++... I came across some thread classes but all of them require Visual Studio... Does anybody know of one? I need one that doesn't need my program to be object-oriented. Thanks! ;-)

Hi Sulf,

Posix threads work fine with C. Hence do not require your program to be object oriented. But it is meant for UNIX based systems like Linux. Not sure it'll work on Windows. It is available with gcc and the corresponding library is "lpthread.a".
Check out for its Windows counterpart.

Hmm... is this the correct way to do it?:

-------------------------
#include <pthread.h>

pthread_t * monsThread;
pthread_attr_t * attrib;
pthread_create(monsThread, attrib, MoveMonsters); // MoveMonsters being a function
-------------------------

That gives me a bunch of error messages... I read the documentation but they don't give an example... do you know how to do it? Thanks! ;-)

Hi sulf,

I did thread programming many days ago and don't quite recall everything. The declaration of pthread_create() is something like -

int pthread_create(pthread_t * thread, pthread_attr_t * attr, void *
(*start_routine)(void *), void * arg);

The first argument is obviously the thread pointer. Second one specifies the attributes you wanna pass to the thread. Third one, the most important one, a pointer to a function that'll run as a separate thread. Note that this function must have a return type of void* and take a viod* as argument, something like

viod* thread_function(void* arg);

The fourth one is the argument that will be passed as an argument to the thread function.

Finally, you MUST link your program to the pthread library as follows

gcc yourprog.c -lpthread

Hmm... does the -lpthread option work on Windows too? I'm still getting a bunch of errors... :-(
Thanks! ;-)
