| | | | | | | | | | | | throughout. * shared.h: Remove. * cygwin_version.h: New file. * delqueue.h: New file. * environ.h: New file. * host_dependent.h: New file. * perprocess.h: New file. * registry.h: New file. * security.h: New file.
* Split out tty and shared_info stuff into their own headers and use throughout.Christopher Faylor2000-09-071-256/+0
| | | | | | | | | | | | | | | | | Include sys/termios.h for files which need it. * tty.h: New file. * shared_info.h: New file. * fhandler.h: Move inline methods that rely on tty stuff to fhandler_console.cc. * fhandler_tty.cc (fhandler_pty_master::process_slave_output): Set output_done_event immediately after reading data to speed up tty output processing. (process_output): Set write_error to errno or zero. (fhandler_tty_slave::write): Check previous write error prior to writing to slave end of pipe. This allows tty output to be slightly less synchronous. * fhandler_console.cc (fhandler_console::tcsetpgrp): Moved here from fhandler.h. (fhandler_console::set_input_state): Ditto.
* * sigproc.cc (proc_info): Rename proc_exists which takes a pid to "pid_exists".Christopher Faylor2000-09-011-51/+0
