Restrictions on the number of file handles opened by Windows system processes

In a Linux system, the limit of the number of file handles open by a process can be viewed and modified using the Ulimit command, or modified/etc/security/limits.conf may also be modified. However, there is no convenient way to view this value in Windows.

The following code can be used to view the value, and the set method has not been found.

The value of the program under Windows Server 2003 is 509, plus standard I/O and standard error file handles, and the system should be 512. Other Windows systems can try the following code if needed.

int _tmain (int argc, _tchar* argv[])

{

FILE *p;

P=fopen ("E:\\first.txt", "RB");

if (p==null)

{

printf ("\nerror on Open e:\\first.txt file!");

}

int i = 1;

while (P!=null)

{

P=fopen ("E:\\first.txt", "RB");

printf ("%d\n", I);

i++;

}

return 0;

}
