We do cygwin development here. OK, so let me ask a bit more precise: VED (and similar nvi) does record locking of edited files by first opening the file with O_RDWR and applying a record lock. Then it opens the the file for reading and reads the file into the buffer. This definitely does not work with Cygwin on Win ME. - Will this work on Win NT ? If not, I could try to re-use the file descriptor from the record locking call for reading in the file and later for writing it out. But then there should definitely a fix in cygwin or a hint in the FAQ.
