does looping wastes processing power

by tech.. » Sun, 26 Nov 2000 04:00:00

currently, i have a process that does nothing but wait for an event to
trigger off periodically.

i use SIGALRM to set the alarm.
the code is something like this

void alarm_handler(){
triggeredprocess();
alarm(15);

Quote:}

int main(){
signal(SIGALRM,alarm_handler);
alarm(15);
while (1) {

}

so my question is, does the infinite loop in the main method waste
processing power?
is there a better way to implement it?

thanks.

1. main loop cpu waste

I am currently developing a daemon that is supposed to check whether there
are any connection attempts by calling select() on a listening tcp/ip
socket. select() is set to immediately timeout, because in the main while()
loop, a function is called that does some unix ipc with other client
processes. you could think of it as an IRC chat server that has to
distribute messages across all of it's clients.

---
sample pseudo code

while(1)
{
select(socket); //timeout==0
ipc_function(); //needs to be called periodically

---

my problem is that the while() loop eats up almost all of my server's cpu
time. is there any practical solution to this problem?

any help would be appreciated!
