[carobee]

hi

i wanted to incorporate a time out feature in while reading message queues in my program. i think i have to use threads but i m not able to visualise the logic.

can anyone help? im in urgent need

Probably you need to use threads.

A thread is a function. The thread runs as long as the function runs.

The function has to have a specific function prototype for it to be usable as a thread function.

Threads are created by _pcreate_thread (Unix/Linux) and CreateThread(Wi ndows).

Start your research there.

thnks for the quick reply
i have to collect the message in php on the other side. what i designed follows like this
1)sent the message from php script to C prog
2)if C prog receives , then sends a ack to php script
3)php script receives the ack from php.meanwhile C prog monitors the message queue for in coming messages. if there is no message the for atleast say some sec, then sends a nack
4)the php script on receiving the nack should time out.

i have finished till step 3, but the prob that im facing is while the C prog is sending the nack, this nack is not able to create the time out feature in php
