From a7cde2b98a658522f552a7ac7ae0a9ef07981e0a Mon Sep 17 00:00:00 2001 From: Christopher Faylor Date: Wed, 17 Jan 2001 14:57:09 +0000 Subject: * autoload.cc (LoadDLLinitfunc): Remove debugging statement. * exceptions.cc (sig_handle_tty_stop): Move setting of PID_STOPPED to earlier in interrupt. ((interrupt_setup): i.e., here. (sig_handle): Don't queue multiple SIGSTOPS. * fhandler.h (bg_check_types): Enumerate return value of bg_check for clarity. * signal.cc (kill_pgrp): Minor cleanup. * fhandler_termios.cc (fhandler_termios::bg_check): Use enumerated type for function return. Don't raise signal if a signal is already queued. * fhandler_console.cc (fhandler_console::read): Use enumerated return type for bg_check. * select.cc: Ditto, throughout. * read.cc: Ditto, throughout. * termios.cc: Ditto, throughout. (_read): YA interrupt detect simplification. * wait.cc (wait4): Ditto. --- winsup/cygwin/fhandler.h | 12 ++++++++++-- 1 file changed, 10 insertions(+), 2 deletions(-) (limited to 'winsup/cygwin/fhandler.h') diff --git a/winsup/cygwin/fhandler.h b/winsup/cygwin/fhandler.h index 356eb6beb..92cf8c300 100644 --- a/winsup/cygwin/fhandler.h +++ b/winsup/cygwin/fhandler.h @@ -122,6 +122,14 @@ class select_record; class path_conv; class fhandler_disk_file; +enum bg_check_types +{ + bg_error = -1, + bg_eof = 0, + bg_ok = 1, + bg_signalled = 2 +}; + class fhandler_base { private: @@ -310,7 +318,7 @@ public: { return windows_device_names[FHDEVN (status)]; } - virtual int bg_check (int) {return 1;} + virtual bg_check_types bg_check (int) {return bg_ok;} void clear_readahead () { raixput = raixget = ralen = rabuflen = 0; @@ -562,7 +570,7 @@ public: int tcgetpgrp (); int tcsetpgrp (int pid); void set_ctty (int ttynum, int flags); - int bg_check (int sig); + bg_check_types bg_check (int sig); virtual DWORD __acquire_output_mutex (const char *fn, int ln, DWORD ms) {return 1;} virtual void __release_output_mutex (const char *fn, int ln) {} }; -- cgit v1.2.3
