(transport_layer_base::write): Ditto. (transport_layer_base::connect): Ditto. 2002-06-16 Conrad Scott <conrad.scott@dsl.pipex.com> * cygserver.cc (check_and_dup_handle): Only use security code if running on NT, i.e. if wincap.has_security(). (client_request_attach_tty::serve): Add check for has_security(). * cygserver_process.cc (process_cache::process): Use DWORD winpid throughout to avoid win32 vs. cygwin pid confusion. (process::process): Ditto. * cygserver_shm.cc (client_request_shm::serve): Only use security code if running on NT, i.e. if wincap.has_security(). * cygserver_shm.h (client_request_shm::parameters.in): Replace the ambiguous pid field with cygpid and winpid fields. (client_request_shm::client_request_shm): Reduce to only two client-side constructors: one for SHM_CREATE, another for all the other requests. * shm.cc (client_request_shm::client_request_shm): Ditto. Initialize cygpid and winpid fields here. On NT initialize sd_buf here using set_security_attribute() to make use of the euid and egid. (shmat): Use new client_request_shm constructor. (shmdt): Ditto. (shmctl): Ditto. (shmget): Ditto. Remove security code, now performed in the relevant client_request_shm constructor. * include/cygwin/cygserver_process.h: (class cleanup_routine): Change winpid type to DWORD. (class process): Ditto. 2002-06-15 Conrad Scott <conrad.scott@dsl.pipex.com> * woutsup.h: New file. * cygserver.cc: Use "woutsup.h" and new XXX_printf macros. (getfunc): New function, copied verbatim from "strace.cc". (__cygserver__printf): New function. * cygserver_client.cc: Use "woutsup.h" and new XXX_printf macros. * cygserver_process.cc: Ditto. * cygserver_shm.cc: Ditto. * cygserver_transport.cc: Ditto. * cygserver_transport_pipes.cc: Ditto. * cygserver_transport_sockets.cc: Ditto. * threaded_queue.cc: Ditto. * shm.cc: Remove trailing \n from XXX_printf format strings. * Makefile.in: Remove special __OUTSIDE_CYGWIN__ case for cygserver_shm.cc.
