http://bugs.winehq.org/show_bug.cgi?id=16957 Summary: CreateProcess handles are inherited even when bInheritHandles=FALSE Product: Wine Version: 1.1.2 Platform: PC OS/Version: Linux Status: UNCONFIRMED Severity: minor Priority: P2 Component: kernel32 AssignedTo: wine-bugs(a)winehq.org ReportedBy: ben(a)salilab.org Created an attachment (id=18729) --> (http://bugs.winehq.org/attachment.cgi?id=18729) test.c The attached file uses CreateProcess to create a subprocess (gzip in this case) with redirected standard output. In order for this to work properly, the output handle created in this code must be inherited by the subprocess - thus the bInheritHandles argument to CreateProcess must be TRUE. And indeed if this program is compiled to test-true.exe, a simple text file 'test.in' and the gzip binary are placed in the same directory, and then test-true.exe is run, it successfully produces the output test.gz. If the TRUE argument is switched to FALSE and the file is compiled again to test-false.exe, when the program is run in the same way on a 'real' Windows sytem (32 bit Vista Business in this case) the following is output: gzip: stdout: Bad file descriptor This is also fine and expected, since the output file handle was not passed to gzip. *However* if the same test-false.exe program is run with Wine (the Fedora 10 wine-core-1.1.12-1.fc10.i386 package in this case) it runs in just the same way as test-true.exe, generating the test.gz output. This suggests to me that the bInheritHandles argument is ignored by Wine. As stated, this is a minor bug but it would be nice if Wine behaved the same way as Windows here. (In our case we discovered this problem after we tested our program successfully under Wine, but then had it fail on a real Windows system.) I am not familiar with the code, but hopefully it should be straightforward enough to provide the subprocess with invalid handles if bInheritHandles=FALSE? -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
