System Functions (s and S) spt_f
flushx(2)
[EINTR] The spt_fflushx() function was interrupted by a signal that was caught.
[EIO] The TOSTOP tty local mode causes a background process to get a SIGTTOU
signal if it attempts to write to the controlling terminal. The SIGTTOU signal, if
it is not caught or ignored, will cause the process to block in a stopped state. A
process in an orphaned process group is not allowed to become stopped, since
there is no unprivileged process to unblock it. This condition only applies to
operations on stdio streams associated with ttys.
[EIO] is also associated with driver errors.
[ENOSPC] There was no free space remaining on the device containing the file.
[EPIPE] An attempt is made to write to a pipe or FIFO that is not open for reading by any
process. A SIGPIPE signal will also be sent to the process.
