Re: Time Outs
Hi,
Thanks Doug for your answer.
But I really need to have different threads, I could join two of them but it
continues beeing more than one thread.
Perhaps my question should be what are the way to creat a timer/Time out...
I know the posix timers but there's another solutions?
Thanks again!

Does it have to be within a single thread? If it was a shell I'd run
"sleep Xs;erase", and similar if I was in python.
The problem with a queue is that for asyncronous input [thread,
processes, whatever], the delay and pointer touples won't be sorted at
all, while ideally they would be sorted by delay.
You could have a separate program that received on stdin touples that it
then turned the delay touple into a specific time-to-erase that then got
sorted. Stdin could be from a named pipe (fifo) from the async
threads/processes.
I know I'm being process-centric but its been years since I used threads
and then only briefly, but the concept of a program component (separate
thread, separate process, or just a function called by the program's
main loop) that pulls the async touples, orders them into a new fifo,
and then processes any erase-requests that have expired, is valid.
Doug.
