Set errno to ENODEV if device not found. * dtable::find_fifo: Define new function. * dtable.h (dtable::find_fifo): Declare new function. * fhandler.cc (fhandler_base::device_access_denied): Fix O_RDONLY test. (fhandler_base::write): Use output file handle for writing. (fhandler_base::fstat): Use is_fs_special rather than is_fs_device. * fhandler.h (fhandler_base::is_fs_special): Rename from is_fs_device. (fhandler_pipe): Make private elements protected so that fhandler_fifo can use them too. (fhandler_pipe::create): New function derived from make_pipe. (fhandler_fifo): Add more needed elements. (fhandler_pty_master::slave): Add to track slave device. (fhandler_pty_master::get_unit): Define. * fhandler_tty.cc (fhandler_tty_master::init): Register slave device. (fhandler_pty_master::open): Ditto. (symlink_info::parse_device): Handle fifo specially. * pinfo.cc (_pinfo::commune_recv): Initial fifo implementation. (_pinfo::commune_send): Ditto. * pinfo.h (picom): Add PICOM_FIFO. * pipe.cc (fhandler_pipe::close): Close input handle here specifically. (fhandler_pipe::create): Rename from make_pipe. Create fhandlers rather than fds. (pipe): Use fhandler_pipe::create to create pipe. (_pipe): Ditto. * syscalls.cc (mknod): Accommodate fifos. --- winsup/cygwin/pinfo.h | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/winsup/cygwin/pinfo.h b/winsup/cygwin/pinfo.h index 89b683f94..3599015cc 100644 --- a/winsup/cygwin/pinfo.h +++ b/winsup/cygwin/pinfo.h @@ -29,11 +29,13 @@ struct commune_result { char *s; int n; + HANDLE handles[2]; }; enum picom { - PICOM_CMDLINE = 1 + PICOM_CMDLINE = 1, + PICOM_FIFO = 2 }; class _pinfo @@ -136,7 +138,7 @@ public: inline void setthread2signal (void *thr) {thread2signal = (pthread *) thr;} void commune_recv (); - commune_result commune_send (DWORD); + commune_result commune_send (DWORD, ...); bool alive (); char *cmdline (size_t &); -- cgit v1.2.3
