From 3e4a1ba07b65506c36f7f40fa76fcee26c400a5c Mon Sep 17 00:00:00 2001 From: Johannes Sixt Date: Thu, 15 Nov 2007 22:22:47 +0100 Subject: [PATCH] Windows: Implement a wrapper of the open() function. The wrapper does two things: - Requests to open /dev/null are redirected to open the nul pseudo file. - A request to open a file that currently exists as a directory on Windows fails with EACCES; this is changed to EISDIR.
