Hello everyone,
I'm working on a program that uses both a TCP with linux socket and a
real-time communication module based on rtnet using rtdm.
My requirement is to use the select function with this 2 types of
communication.
To make this works, I created a wrap on select that is calling a function ("
wrap_select") to create two threads in detached mode: the first for linux
descriptors and the second for rtdm descriptors.
After the creation of threads, the "wrap_select" function that waits
for a semaphore.
This semaphore is posted by the thread which select is released.
Then the function "wrap_select" destroy the two functions with
pthread_cancel.
This mechanisme works fine but after a certain number of calls, creating
thread with pthread_create fails with the following error: errno = EAGAIN,
Insufficient memory exists in the system heap to create a new thread,
Increase.
It seems there was a limit to the thread creation...
1 - Have you any idea about how to work around this problem?
2 - A solution would be to create two threads to handle rtdm select and
linux without destroying them each time.
But in this case I have to report to the select which thread is still blocking
its release and I dont know how I can do that.
3- Maybe there is a better solution or maybe this problem has already been
encountered and solved by one of you?
Regards,
Alexandre
