/* fhandler_virtual.h: Header for virtual fhandlers
* Makefile.in (DLL_OFILES): Add fhandler_procsys.o. * devices.h (enum fh_devices): Add FH_PROCSYS. * devices.in (dev_procsys_storage): New device. * devices.cc: Regenerate. * dtable.cc (build_fh_pc): Add code to allocate fhandler_procsys. * fhandler.h (proc_len): Convert to size_t. (procsys): Declare. (procsys_len): Declare. (enum virtual_ftype_t): Move here from fhandler_virtual.h. Add members supported by fhandler_procsys. (fhandler_virtual::exists): Return virtual_ftype_t. Change in all derived classes. (class fhandler_procsys): New class. (fhandler_union): Add fhandler_procnet and fhandler_procsys members. * fhandler_disk_file.cc (__DIR_mounts::check_missing_mount): Use ro_u_proc. (fhandler_base::fstat_by_handle): Don't copy attributes if file is an NT device. (fhandler_base::fstat_by_name): Ditto. * fhandler_netdrive.cc (fhandler_netdrive::exists): Return virtual_ftype_t. * fhandler_proc.cc (proc_tab): Sort alphabetically. Use _VN macro to store length. (proc_len): Change to size_t. (proc_tab_cmp): New static function. (virt_tab_search): New function to search entry in virt_tab_t arrays. Use throughout in /proc and sibling classes instead of loop. (fhandler_proc::exists): Return virtual_ftype_t. * fhandler_process.cc (process_tab): Sort alphabetically. Use _VN macro to store length. (fhandler_process::exists): Return virtual_ftype_t. (fhandler_process::open): Simplify code. * fhandler_procnet.cc (procnet_tab): Sort alphabetically. Use _VN macro to store length. (fhandler_procnet::exists): Return virtual_ftype_t. (fhandler_procnet::open): Simplify. * fhandler_procsys.cc: New file. * fhandler_registry.cc (fhandler_registry::exists): Return virtual_ftype_t. * fhandler_virtual.cc (fhandler_virtual::exists): Ditto. * fhandler_virtual.h (enum virtual_ftype_t): Move to fhandler.h. (virt_tab_t): Add name_len member. (_VN): New macro. (virt_tab_search): Declare. * mount.cc (mount_info::conv_to_win32_path): Fix comment. Backslashify isprocsys_dev paths. * ntdll.h (STATUS_OBJECT_TYPE_MISMATCH): Define (STATUS_INSTANCE_NOT_AVAILABLE): Define. (STATUS_PIPE_NOT_AVAILABLE): Define. (STATUS_INVALID_PIPE_STATE): Define. (STATUS_PIPE_BUSY): Define. (SYMBOLIC_LINK_QUERY): Define. (NtOpenSymbolicLinkObject): Declare. (NtQuerySymbolicLinkObject): Declare. * path.cc (path_conv::check): Accommodate fact that exists method returns virtual_ftype_t now. Add cases for new virtual_ftype_t types. (cygwin_conv_path): Add GLOBALROOT prefix to native device paths. Make sure to strip \\?\ prefix only for actual filesystem-based paths, not for all paths. * path.h (isproc_dev): Add FH_PROCSYS. (isprocsys_dev): Define.
