Why is SIGPIPE not blocking?

Question

linux

Hello.
The program works with a socket. To prevent the SIGPIPE signal from flying out, I block it:
sigset(SIGPIPE, SIG_IGN);
But the execution is still completed by the SIGPIPE signal during the send execution:
ssize_t size = send(socket, data, currentSize, 0);

If the MSG_NOSIGNAL flag is set, then the signal will stop flying. But this method works under Linux, but does not work under Solaris.

Why is the signal not blocked?
