Hi Nilesh,
Concerning the number of simultaneously open files, the limitation is not in
Windows, but in the stdio level, this number can be increased to a maximum
of 2.048 files per program.
Calling _setmaxstdio(2048); in the main() function before initializing
quickfix, will make it possible to create about 340 sessions using
FileLogFactory and FileStoreFactory together, if the application needs to
open other files, this number of sessions will certainly have to decrease.
This is not so bad, but I am really thinking about a genuine Win32
implementation for these factories, calling the API functions directly and
not using stdio will definitively eliminate this kind of limitation and the
performance will become better too.
If you plan to have multiple sessions, prefer the threaded-socket classes.
