I have been trying to understand the Posix client library. I have two
1. I can't figure out the Fstat function in XrdPosixXrootd.cc (~line
201). Even though there is a write interface, the Fstat method seems to
assume that the value from the last stat (probably the Open) is still
valid. Why doesn't it do a new fstat call to the server each time to
get the current values for the file?
2. I have poked around in the Posix standard for the maximum valid
value for a file descriptor, without success. The Posix client library
assumes that 65K is the maximum value a file descriptor can take on. Is
this limit from the Posix standard, or is it based on "nobody will ever
use that many files descriptors"?
