On the contrary, it's easy to underestimate the problem :) If you are using a stdio replacement, (such as sfio), then you are more-or-less safe from the problem. The problem is that the native libc will not allow file descriptors with a numerical value > 255, regardless of your per-process file descriptor limit.

I don't think this is true. #include "stdio.h" #include "fcntl.h" int main() {

        int i = 0;
        int fd = 0;
        while(1) {
                char path[11];
                snprintf(path, 11, "/tmp/t/%d", i++);
                if((fd = open(path, O_RDWR|O_CREAT, 0)) < 0 ) {
                        return;
                }
                printf("Opened fd: %d number %d\n", fd, i);
        }

} created me 1021 fd's as a non-priv'd user on my Sol 2.6 system (with it's standard libc). The problem is with the stdio routines (fopen et. al.). As long as you don't use fopen you're set.
