[SOLVED] opening many threads and waiting for certain event

[syedshan]

hello every one,

I need to open more than 500 threads and each thread (except for the one I call the master thread, although it is the same PARALLEL thread with others).
Total "500 + 1" threads

I want my master thread to receive data from DMA, then activate something in the other threads. Where I copy data using memcpy() to the buffer in that thread. and then in the mean time, the next data comes from DMA in the master thread, which activates the other file-saving thread and so on...

(note that each thread correspond to each file-saving-thingy, hence 500 files).

I really am messed up for two days reading loads of material over threads (in c++) mainly starting from createthreads() and going on and on, I thought the WaitForSingleObject might be solution but I cannot understand how to implement this...

any idea would be appreciable. I do not seek any code, I just seek the way to implement. For example those familira with VHDL, they might know in VHDL we can use

wait until abc'event and abc = '1';

but what to do here?

thanks
Shan

well we can do that in several ways, for exampl WaitForSingle event or WaitForMultiple event or the function who is calling the calling after the CreateThread() statement infinite while loop as shown below.

while(1) {

//if(certain global flag triggers)
break;
}
