| | | | | | | | | | * *.cc: put winsup.h before other headers (for __INSIDE_CYGWIN__); use cur_environ() instead of just environ * times.cc: remove import protections * glob.c: add winsup.h * localtime.c: ditto * smallprint.c: ditto * Makefile.in: don't __INSIDE_CYGWIN__ as it messes up profiling.
* * fhandler.h (class fhandler_dev_raw): Add private member `varblkop'Corinna Vinschen2000-07-231-25/+38
| | | | | | | | | | | | | to be set when variable blocksize mode is on. * fhandler_raw.cc: Eliminate `\n' from trace output. (clear): Set `varblkop' to 0. (dup): Copy varblkop as well. (writebuf): Care for variable blocksize. (open): Ditto. (raw_read): Ditto. (raw_write): Ditto. * fhandler_tape.cc (open): Ditto. (ioctl): Ditto. Some cleanups.
* Throughout, eliminate third argument to path_conv and use new PC_* constantsChristopher Faylor2000-07-171-1/+1
| | | | | | | | | | | | | | | | | | for second argument. * path.h: Generalize SYMLINK_* constants to PC_*. (path_conv): Create a new method. Fold third argument into second. * dll_init.cc (dll_list::alloc): Try harder to find space to allocate dll struct. (dll_dllcrt0): Don't check sanity if we've already called dll_crt0. * path.cc (path_conv::check): Don't check for a null or empty path unless specifically told with a flag setting. (check_null_empty_path): New function, adapted from macro. * syscalls.cc (_rename): Use already-determined file attributes rather than checking again. * lib/cygwin/cygwin_attach.dll.c (cygwin_attach_dll): Use a static per_process structure since this is apparently supposed to be zeroed. * lib/cygwin_crt0.c (cygwin_crt0): Zero per_process structure sent to older DLLs.
* * fhandler_raw.cc (write_file, read_file): New wrapper functionsCorinna Vinschen2000-05-121-22/+51
| | | | | | | for WriteFile and ReadFile to get rid of ERROR_MEDIA_CHANGED and ERROR_BUS_RESET in case of first access to tape. (fhandler_dev_raw::raw_write): Use write_file instead of WriteFile. (fhandler_dev_raw::raw_read): Use read_file instead of ReadFile.
