Exporting the value of errno would be really useful here. However: the value would be OS specific which would damage PHP program portability. Maybe a function like get_last_os_error() might be appropriate. This would return is PHP error number, ie map OS specific info (which is sometimes more than just errno) onto something OS independent. This might be a non tiny amount of work, but is only done if the application *really* wants/needs to know. What the function might return could be an array, where different elements contain different levels of details - including the OS specific stuff (some people are not bothered by portablity).
