Re: [libvirt] [PATCH v3 1/4] util: new function virFileLength()

This new function just calls fstat() (if provided with a valid fd) or stat() (if fd is -1) and returns st_size (or -1 if there is an error). We may decide we want this function to be more complex, and handle things like block devices - this is a placeholder (that works) for any more complicated function. --- Changes from V2: * add fd arg and use it to optionally call fstat() instead of stat. * return -1 unless it is a "regular file" (i.e. not a block device). Is this what you were thinking of Eric?
