As usual, commercial support is just making things up. This one is easy to actually test.
#include <unistd.h>
#include <stdio.h>
int main (void) {
printf("current file limit: %d\n",getdtablesize);
exit (0);
}
Compile it, run it, viola!
$ gcc getdtablesize.c
$ ./a.out
current file limit: 134513392
(results will vary).
