I would like to use SIGUSR1 and SIGUSR2 as arguments to pthread_kill() to suspend the execution of the running thread(i.e thread sends signal to itself) and resuming a suspended thread by a peer thread when a condition is met.
Would be gratefull for any pointers like example code or views about it.
Thanks
While I agree with Nemo, there are some valid use cases for suspending threads via signals. The
susp.ccode in PWPT is certainly a good base but you can also find it used in GLIBC. You might also wish to break the thread out of a blocking-IO system call (see this question) or interrupt a semaphore wait (see this question).
