System Functions (s and S) spt_putwcx(2)
[EAGAIN] The O_NONBLOCK flag is set for the file descriptor underlying stream and the
process would be delayed in the write operation.
[EBADF] The file descriptor underlying stream is not a valid file descriptor open for writ-
ing.
[EFBIG] An attempt was made to write to a file that exceeds the process’s file size limit or
the maximum file size.
[EILSEQ] The wide character code specified by the c parameter does not correspond to a
valid character.
[EINTR] The operation was interrupted by a signal that was caught, and no data was
transferred.
[EIO] The implementation supports job control; the process is a member of a back-
ground process group attempting to write to its controlling terminal; TOSTOP is
set; the process is neither ignoring nor blocking SIGTTOU; and the process
group of the process is orphaned.
[ENOMEM] Insufficient storage space is available.
[ENOSPC] No free space was remaining on the device containing the file.
[ENXIO] A request was made of a nonexistent device, or the request was outside the capa-
bilities of the device.
[EPIPE] An attempt was 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.
