Hi,
I know that conditional variable can be used inter-process,
but need to initialized with PTHREAD_PROCESS_SHARED,and should
be in the shared memory. But I do not know how to do that, I
just use:
pthread_condattr_init(&cv_attr);
if ((n=pthread_condattr_setpshared(&cv_attr,
PTHREAD_PROCESS_SHARED))!=0){
fprintf(stderr, "condattr wrong");
exit(1);
}
if ((n=pthread_cond_init(&EmptyCond,&cv_attr))!=0){
fprintf(stderr, "cond_init");
exit(1);
}
What other things should I do?
Thank you!
