If the si_code field indicates the source is SI_SIGIO, the si_fd field gives the file descriptor associated with the event.

WebThe sigaction() system call assigns an action for a signal specified by sig. If act is non-zero, it specifies an action (SIG_DFL, SIG_IGN, or a handler routine) and mask to be used when delivering the specified sig- nal. If oact is non-zero, the previous handling information for the sig- nal is returned to the user.
