How to get write permission status

zhisong

Hi,

To check cell editable information before open it, I try to use ddGetObj(lib cell view)~>isWritable

In my situation, I use design management software. Now before I check out the cell, of course I can't edit it, but the isWritable is t.

And I can find permission of all database  444. Is that a bug of IC5.1?

So any other way to check the editable info?

Thanks

 Jason

    Hi Jason

    This is actually not a bug of IC5141. Virtuoso uses linux access() cmd to check for file permissions and as stated in "man access" (type "man access" in a terminal window), this cmd sometimes does not work properly for certain settings on linux NFS systems. You can do something like this:

    system("stat myfile | egrep Access > /tmp/check")
    inPort=infile("/tmp/check")
    fscanf(inPort "Access: (%d/" permission)
    close(inPort)
    printf("File permission is : %d\n" permission)

    I think there must be a better workaround than this. Maybe Andrew or Lawrence might have a better idea. : )

    Best regards
