Shan Bell) Newsgroups: comp.os.386bsd.questions Subject: [FreeBSD] read/write error to non-blocking ptys Date: 14 Feb 1994 17:12:30 GMT Organization: Msen, Inc. -- Ann Arbor, Michigan Lines: 16 Distribution: world Message-ID: <2jobdu$la@nigel.msen.com> NNTP-Posting-Host: 192.245.33.3 Keywords: pty, FreeBSD Can anyone confirm this problem and/or suggest a work around? While either reading from or writing to file descriptors that belong to non-blocking ptys I get "Resource temporarily unavailable" (errno == EAGAIN). The problem does not occur is I'm using a tty or if the operation is not non-blocking. If this is a problem with the tty driver, then I would be willing to debug it with some direction. I really need this ability. thanks, shan -- J. Shan Bell Cybernet Systems Corporation shan@cybernet.com Research and Development (313) 668-2567 Ann Arbor, MI
