What is the windows equivalent of the unix command " ulimit -n" ?
Basically, i want to set the maximum fd limit via command prompt.
hmm... I may have been wrong before - setmaxstdio (see here) - but it is per-process, not system wide.
I may be wrong, but I didn't think there was a limit to set in Windows... but unless you can say how this relates to programming, I expect this answer will be closed soon.
If you are in the "IT Pro" area (rather than development), then there is a sister-site, serverfault.com - coming soon for this type of question.
I don't believe that current Windows O/S have a limit on the total number of file descriptors, but the MS runtime library (msvcrt.dll) has a per process limit of 2048, albeit as far as I know that's not enforced by the O/S.
It can allegedly be increased only by building your own version of the MS runtime library from source.
