This is generally around 2GB, but most modern file systems support much larger files, sometimes requiring 64-bit versions of the read()/write() and lseek() functions.EINTR -- The function was interrupted by a This allows some pretty sophisticated trickery. So both streams end up pointing to file. An exit value greater than 255 returns an exit code modulo 256. http://www-numi.fnal.gov/offline_software/srt_public_context/WebDocs/Errors/unix_system_errors.html

A good puzzle will wake me up Many. Examples: $ who > names Direct standard output to a file named names $ (pwd; ls -l) > out Direct output of both commands to a file named out $ pwd; Get started now with Eclipse: Get more information and links to all things Eclipse. The libraries had to use other conventions for reporting errors.While you're pouring over the C library, or almost any other UNIX library, you'll discover two common ways of reporting failures:The function

Historical applications (that is, horribly outdated legacy code) sometimes refer to these directly, but produce errors during compilation because they're declared inconsistently.The POSIX standard defines quite a few possible values for http://unix.stackexchange.com/questions/154868/make-all-error-2 This would allot 50 valid codes, and make troubleshooting scripts more straightforward.

They are supported on UNIX systems by other languages (C++, Objective-C, Python, and so forth). http://crimsonskysoftware.com/error-code/unix-error-25.html When errno is set to 0, you've encountered no problems, except you can't refer to this with a standard symbolic constant.

Luckily, most functions will only have a few possible errors to report, so it's usually not that hard to handle them appropriately.Back to topDealing with errorsAdding error-handling code to your program Note that it isn't guaranteed that any given program will use these return values.
