Problem about Sparc/solaris10 signal in multi-thread environment
Normally if we send a signal to a process which has several threads, the main thread of this process will handle this signal. But I found in some cases an other thread (not main thread) handled signals even if main thread was alive(mostly main thread was being blocked by __pollsys()).
I want to know why and how this happens.
Thanks.
