- Subject: [ECOS] cyg_thread_resume question
I have a question regarding following lines from eCos reference guide:
"cyg_thread_suspend can be used to increment the suspend counter, and
cyg_thread_resume decrements it. The scheduler will never run a thread with
a non-zero suspend counter"
Does it mean that resuming a thread without varify if it is sleeping or not
can lead the thread to be non-runnable? For example a thread X is in ready
state but not getting executed because some higher priority thread Y is
running. Now thread Y calls cyg_thread_resume(X). This will decrement the
suspend counter of thread X, which was already zero. Will the thread X now
ever run?
