I seem to recall a thread earlier on this limitation, but looking at actual libc/stdio sources, the 4 year old check for open(2)'s fd being less than SHRT_MAX is still there. I thought I saw a patch to change this to an int, but it's not in the tree. Was this in a PR or a mailing list thread or am I just imagining things? We've run into this limitation at work, where some processes have around 32k open file descriptors and then try to use the libc FILE interface. Since we control ABI we can just change this to int, but I had been hoping there was a FreeBSD revision we could pull instead of having another diff. Thanks, matthew
