hot to get a return value from a function executed by a pthread

[rpjanaka]

hi all,

i want to execute a function by a separate thread and get that functions return value in to the main thread.

one way to do this is set a global variable by that separate thread and access that variable from the main thread. This procedure is as follow.

int tid = 0; // global variable

void *PrintHello(void *threadid)

{

tid = (int)threadid;
// set the global variable by a separate thread
}

int main (int argc, char *argv[])

{

pthread_t threads[NUM_THREADS];

int rc, t;

for(t=0; t

Look up pthread_exit() and pthread_join() for ways of communicating information from the thread back to the parent.
