[MPICH] Semaphores Discussion Forum

[William Gropp]

Most Unix system calls will return this error.  Typically, you need  
something like

do {
     err = systemcall(...);
} while (err == -1 && errno == EINTR);

There are times when you may want to do something else after a signal  
handler operates, but this code is what is usually required.
