maximum number of times - a file can be opened
Hi All,
We can find the maximum of open file descriptors in hold with respect to a process.
As default size was 256 (with getrlimit) and the hard limt was 65536
I tried changing the limit to 1024(with setrlimit)
successfully changed the limit
but still I couldnt have as many open file descriptors as I had mentioned in the setrlimit, I am just pushed off with 256 file descriptors itself.
And one more,
Though the process has limitations on the number of file descriptors it can have, is there any limit imposed indirectly on a file that it can have only 'n' number of active open(s).
(virtually, I think it is not possible). say, File dum.c can be opened only 'Z' no of times.
Any ptrs for the above!!!
Thanks.
