Subject [jira] Updated: (HARMONY-6642) [classlib][luni] FileInputStream doesn't close FD in native code
Date Fri, 03 Sep 2010 08:07:34 GMT

     [ https://issues.apache.org/jira/browse/HARMONY-6642?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Shi Jun Zhang updated HARMONY-6642:
-----------------------------------

    Attachment: HARMONY-6642.diff

Refer to https://issues.apache.org/jira/browse/HARMONY-826
The above issue was not fixed correctly. The root cause why new FileInputStream(FileDescriptor.in).close()
throw exception is that the file handle of stdin on windows is not 0. File handles of stdin/stdout/stderr
should be got through GetStdHandle() system method.
So my patch add native method to get file handles for stdin/stdout/stderr. On linux, they
are 0/1//2, but on windows, they are returned by GetStdHandle() method.
