(cfsetospeed): Use setspeed to set speed. (cfsetispeed): Use setspeed to set speed. * autoload.cc: Add load statement for UuidCreate, and UuidCreateSequential. * cpuid.h: New file. * cygwin.din: Export gethostid. * fhandler_proc.cc (cpuid): Move to cpuid.h. (can_set_flag): Move to cpuid.h. * syscalls.cc (gethostid): New function. * version.h: Bump DLL minor version number to 83. --- winsup/cygwin/ChangeLog | 21 ++++++- winsup/cygwin/autoload.cc | 3 + winsup/cygwin/cpuid.h | 35 +++++++++++ winsup/cygwin/cygwin.din | 1 + winsup/cygwin/fhandler_proc.cc | 32 +--------- winsup/cygwin/include/cygwin/version.h | 3 +- winsup/cygwin/syscalls.cc | 109 +++++++++++++++++++++++++++++++++ winsup/cygwin/termios.cc | 46 ++++++++++++-- 8 files changed, 212 insertions(+), 38 deletions(-) create mode 100644 winsup/cygwin/cpuid.h diff --git a/winsup/cygwin/ChangeLog b/winsup/cygwin/ChangeLog index 454b756cd5..49498f3cb5 100644 --- a/winsup/cygwin/ChangeLog +++ b/winsup/cygwin/ChangeLog @@ -1,8 +1,25 @@ +2003-04-15 Christopher Faylor + + * termios.cc (setspeed): New function. + (cfsetospeed): Use setspeed to set speed. + (cfsetispeed): Use setspeed to set speed. + +2003-04-15 Chris January + + * autoload.cc: Add load statement for UuidCreate, and + UuidCreateSequential. + * cpuid.h: New file. + * cygwin.din: Export gethostid. + * fhandler_proc.cc (cpuid): Move to cpuid.h. + (can_set_flag): Move to cpuid.h. + * syscalls.cc (gethostid): New function. + * version.h: Bump DLL minor version number to 83. + 2003-04-15 Thomas Pfaff * thread.h (pthread_rwlock::release): New method. - * thread.cc (pthread_rwlock::unlock): Use release to signal - waiting threads. + * thread.cc (pthread_rwlock::unlock): Use release to signal waiting + threads.
