codes can’t occur on GNU systems, but they can occur using the GNU C Library on other systems. Macro: int c error function EPERM Operation not permitted; only the owner of the file (or other c error codes resource) or processes with special privileges can perform the operation. Macro: int ENOENT No such file or c error handling best practices directory. This is a “file doesn’t exist” error for ordinary files that are referenced in contexts where they are expected to already exist. Macro: int ESRCH No process c programming error codes matches the specified process ID. Macro: int EINTR Interrupted function call; an asynchronous signal occurred and prevented completion of the call. When this happens, you should try the call again. You can choose to have functions resume after a signal that is handled, rather than failing with EINTR; see Interrupted Primitives. Macro: int EIO Input/output error; usually used

for physical read or write errors. Macro: int ENXIO No such device or address. The system tried to use the device represented by a file you specified, and it couldn’t find the device. This can mean that the device file was installed incorrectly, or that the physical device is missing or not correctly attached to the computer. Macro: int E2BIG Argument list too long; used when the arguments passed to a new program being executed with one of the exec functions (see Executing a File) occupy too much memory space. This condition never arises on GNU/Hurd systems. Macro: int ENOEXEC Invalid executable file format. This condition is detected by the exec functions; see Executing a File. Macro: int EBADF Bad file descriptor; for example, I/O on a descriptor that has been closed or reading from a descriptor open only for writing (or vice versa). Macro: int ECHILD There are no child processes. This error happens on operations that are supposed to manipulate child processes, when there aren’t any processes

There are two ways I've been thinking of: Always return error code. A typical function would look like this: MYAPI_ERROR getObjectSize(MYAPIHandle h, int* returnedSize); The always provide an error pointer approach: int getObjectSize(MYAPIHandle h, MYAPI_ERROR* returnedError); When using the first approach it's possible to write code like this where the error handling check is directly placed on the function call: int size; if(getObjectSize(h, &size) != MYAPI_SUCCESS) { // Error handling http://stackoverflow.com/questions/385975/error-handling-in-c-code } Which looks better than the error handling code here. MYAPIError error; int size; size = getObjectSize(h, &error); if(error != MYAPI_SUCCESS) { // Error handling } However, I think using the return value for returning data makes the code more readable, It's obvious that something was written to the size variable in the second example. Do you have any ideas on why I should prefer any of those approaches or perhaps mix them or use something else? I'm not a fan of global error states since it tends to make multi threaded use of the library way more painful. EDIT: C++ specific ideas on this would also be interesting to hear about as long as they are not involving exceptions since it's not an option for me at the moment... c error-handling share|improve this question edited Nov 6 '13 at 19:09 ubershmekel 3,61513144 asked Dec 22 '08 at 10:46 Laserallan 6,70172956 add a comment| 17 Answers 17 active oldest votes up vote 49 down vote accepted I like the error as return-value way. If you're designing the api and you want to make use of your library as painless as possible think about these additions: store all possible error-states in one typedef'ed enum and use it in your lib. Don't just return ints or even worse, mix ints or different enumerations with return-codes. provide a function that

If the issue is caused by #1, you can reinstall the Runtime components of Visual C++ Libraries to resolve the problem. Microsoft Visual C++ 2008 Redistributable Package (x86) http://www.microsoft.com/downloads/details.aspx?familyid=9B2DA534-3E03-4391-8A4D-074B9F2BC1BF&displaylang=en If the issue still persists after installing above package, the issue should be a software problem. I suggest you take a clean boot check whether it is a software conflict issue. If not, it is still recommended to address the problem with man
