I would recommend always writing code to handle EINTR. See Job Control, for information on process groups and these signals. this contact form

EINTR is considered only from 3rd listing on. Some socket functions don’t make sense for all types of sockets, and others may not be implemented for all communications protocols. As a result, the signal handler can only execute during the pselect(), so it is safe to only check the flag after pselect() returns. I read a program it has : if (errno == EINTR) in that program , if this is true, it will continue... http://www.gnu.org/s/libc/manual/html_node/Error-Codes.html
