Say I want to perform the action at a certain timeout, like fire an
event. I figured out how to do every n number of seconds, but not 1.5
seconds. Here is what I have.Please suggest how to handle my case:
extern int PUBLISH_TIMEOUT;
void Publish()
{
static int local_time=time(NULL);
int current_time = time (NULL);
if((current_time+PUBLISH_TIME)>local_time)
{
fireEvent();
local_time=current_time;
}
}

Read the man page for the time(2) system call:
$ man 2 time
Then, follow the SEE ALSO section and examine in
turn each of the references.

There are probably numerous ways, but the most frequent I've
seen has been to do a poll or a select with a timeout and an
empty list of fd's. If your system supports it, you should use
nanosleep. (According to the Posix documentation, it is
optional. But most systems have it, I think.)
