- Subject: [ECOS] Detect if scheduler locked?
I'm trying to make a function work properly if called when the
scheduler is locked.
In order to do this right, the function needs to know whether
it can call cyg_thread_delay(). If the scheduler is locked, it
will have to use some sort of delay loop rather than call
cyg_thread_delay(). It would be trivial to get it would work
right if cyg_current_time() continued to increment while the
scheduler was locked, but it doesn't (probaby requires the
timer DSR to run).
How does application code determine if the scheduler is locked?
