* If EAGAIN and/or EWOULDBLOCK are defined, we can't just return -1 in all

|
|
*
|
|
* On AIX 4.1.5 (and presumably some other versions and OSes), as you
|
|
* perform the manual test suite in the README, if you 'bg' vi immediately
|
|
* after suspending it, all is well, but if you wait a few seconds,
|
|
* usually ioctl() will return -1, which previously caused tty_setty() to
|
|
* return -1, causing Rawmode() to return -1, causing Inputl() to return
|
|
* 0, causing bgetc() to return -1, causing readc() to set doneinp to 1,
|
|
* causing process() to break out of the main loop, causing tcsh to exit
|
|
* prematurely.
|
|
*
|
|
* If ioctl()'s errno is EAGAIN/EWOULDBLOCK ("Resource temporarily
|
|
* unavailable"), apparently the tty is being messed with by the OS and we
|
|
* need to try again. In my testing, ioctl() was never called more than
|
|
* twice in a row.
|

*
