System V message queues

Posted by pjod1 [send private reply] at September 20, 2002, 08:30:53 AM

I'm using system v message queues to pass data between two separate processes (running on Linux). Most of the time there is no problem adding messages to the queue, but sometimes I keep getting the error showed below.

if (msgsnd(msqid, data, size(data), IPC_NOWAIT) < 0)

Reported error:
'msgsnd: Resource temporarily unavailable'

I can't see any problem with my code. Also any time I get the error it wasn't because I exceeded the limit of messages
allowed on the queue.

Any help would be great!
