class function pointer problem.

Hey,

I got a compile problem when i try to use the Thread funcs in my structs/classes.

Second about thread pools. I want to make a list of threads and run them. But im not sure if the function: MultiThreadedCall does this for you. If so can u give me more information about how to use it?

PHP Code:

error C3867: 'classRS::ThreadS': function call missing argument list; use '&classRS::ThreadS' to create a pointer to member 

Code snippet:

PHP Code:

class classRS
{
    Bool ThreadS(Thread &threadCaller);
    
    Thread s;
}


Bool classRS::ThreadS(Thread &threadCaller)
{
    RSS &obj=*(RSS*)s.user;
    obj.Update();

    return false;
}

void classRS::Main()
{
_s = new RSS();
    
s->create(ThreadS, 2, 0, 0, _s);
} 

I get the compile error on line: s->create(ThreadS, 2, 0, 0, _s);

Thnx,

~Dynad

if you declare function inside class, then you need to make it static
class
{
static Bool ThreadS(...) // <-add static
}

MultiThreadedCall executes a given function for specified amount of times, this is used for processing purposes (you have a function that processes data which you need to execute 100 times), so most efficient on a quad core machine, is execute it 25 times on each of 4 cores simultaneously. that's what MultiThreadedCall does.

- Yea adding static fixed the problem, thx

- Ok that makes more sense now... its very handy for preprocessing data smile
