Hello,
I am a new user of the pthread(POSIX thread), and I do not
know that how let each thread handle signal seperately, Maybe
the following example can make it more clearly.
A, B ,and C are three pthread of one process,
A send SIGUSR1 to B, and C,
In B:
BHandler() is function to handle SIGUSR1;
sigaction(....);
In C:
CHandler() is function to handle SIGUSR1;
sigaction(...);
in C:
pthread_kill(Bpthread, SIGUSR1);
pthread_kill(Cpthread, SIGUSR1);
But it seems that only B or C can handle SIGUSR1.
Please give some information. Thank you!
