It would've been nice to have this covered in the specification in order to avoid doing this sort of thing.Listing 4. Your system may have automounted it (usually they are set up that way), but must be manually (in GUI or CLI tool) unmounted or ejected before you can safely remove it. have a peek here
true !true # No error this time, but no negation either. # It just repeats the previous command (true). # =========================================================== # # Preceding a _pipe_ with ! Macro: int EMLINK Too many links; the link count of a single file would become too large. Listing 3 shows you how to use this thread-safe version.Listing 3. Or might not. http://www-numi.fnal.gov/offline_software/srt_public_context/WebDocs/Errors/unix_system_errors.html
The no error error value#if !defined( EOK ) # define EOK 0 /* no error */ #endifUsing the sys_nerr global variable and the strerror() function, you can easily whip up some The author of this document will not do fixups on the scripting examples to conform to the changing standard. IBM ID:*Need an IBM ID?
The programmer needs to know whether the read returned because it got its data, because there is no more data, or if a signal interrupted it. The file was the wrong type for the operation, or a data file had the wrong format. You really need to know what error number 17 means. Errno.h In C Macro: int ENOTEMPTY Directory not empty, where an empty directory was expected.
Send me email. (OLDER) <- More Stuff -> (NEWER) (NEWEST) Printer Friendly Version Home -> Unix Articles -> Numeric Unix Error Messages 4 comments Increase ad revenue 50-250% with Linux Errno Example Level? Some socket functions don’t make sense for all types of sockets, and others may not be implemented for all communications protocols. http://www.thegeekstuff.com/2010/10/linux-error-codes Keep it simple 2.
You can use select to find out when the operation will be possible; see Waiting for I/O. Efault This should not cause any problems, since there is no overlap or conflict in usage of exit codes between compiled C/C++ binaries and shell scripts.PrevHome
You can also use this mechanism to log errors by closing STDERR and reopening the channel to a file. https://www.ibm.com/developerworks/aix/library/au-errnovariable/ You can use the select function to find out when the pending operation has completed; see Waiting for I/O. Posix Error Codes All the error names specified by POSIX.1 must have distinct values, with the exception of EAGAIN and EWOULDBLOCK, which may be the same. Linux Errno To String For example, here's the places where EPERM is referenced on a 7.2 Red Hat system: acct.c capability.c fork.c kmod.c module.c printk.c ptrace.c sched.c signal.c sys.c sysctl.c time.c uid16.c On Apple OS
Just remember to pull out 3 in the morning 3. navigate here Macro: int ESPIPE Invalid seek operation (such as on a pipe). This indicates an internal confusion in the file system which is due to file system rearrangements on the server host for NFS file systems or corruption in other file systems. Perhaps you'd get this if you had a recursive directory looping back on itself. #define EPIPE 32 /* Broken pipe */ Fairly obvious- the reading or writing side of a pipe Errno.h Windows
echo $? # Non-zero exit status returned -- command failed to execute. Thank you @Keith! Create A New User Node Status? http://crimsonskysoftware.com/error-code/unix-system-error-32.html Macro: int EADDRINUSE The requested socket address is already in use.
Showing the declaration of errnoIn addition to noticing that my tab settings don't match those of whoever wrote this file, you'll see several of the standard error values, their symbolic names, Enotsup You can look at this file on your system to see the numerical values. Note the ambiguity between EBUSY and EAGAIN; obviously you'd be able to remove the directory later, when the reading program has finished.ECHILD -- The wait() or waitpid() function tried to wait

Enxio Macro: int EINPROGRESS An operation that cannot complete immediately was initiated on an object that has non-blocking mode selected.
Macro: int EDIED On GNU/Hurd systems, opening a file returns this error when the file is translated by a program and the translator program dies while starting up, before it has So, the thing to keep in mind is that just because you've seen a particular error on a particular platform doesn't mean it is the same somewhere else. If you get this error, you might want to increase the RLIMIT_NOFILE limit or make it unlimited; see Limits on Resources. http://crimsonskysoftware.com/error-code/unix-system-error-11.html Macro: int EILSEQ While decoding a multibyte character the function came along an invalid or an incomplete sequence of bytes or the given wide character is invalid.
Each of these drivers has "stubs.c" code -- code that gets linked into the kernel when the driver is _not_ present -- that returns ENOPKG for certain operations.
