Macro: int ENOSYS Function not implemented. A temporary resource shortage made an operation impossible. errno.errorcode¶ Dictionary providing a mapping from the errno value to the string name in the underlying system. I've seen that segmentation faults often result in an exit status of 11, though I don't know if this is simply the convention where I work (the apps that failed like his comment is here
Macro: int ERANGE Range error; used by mathematical functions when the result value is not representable because of overflow or underflow. Some functions that must always block (such as connect; see Connecting) never return EAGAIN. In any of these cases, they exit 0 despite failing. As I saw few standard error codes are located in arch/powerpc/boot/stdio.h and other scattered at various other places.. http://www-numi.fnal.gov/offline_software/srt_public_context/WebDocs/Errors/unix_system_errors.html
I have to investigate why they weren't defined in the main errno header Michael B Allen
Macro: int EPIPE Broken pipe; there is no process reading from the other end of 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. UNIX is a registered trademark of The Open Group. Errno.h Linux Kernel The following error codes are defined by the Linux/i386 kernel.
The author of this document proposes restricting user-defined exit codes to the range 64 - 113 (in addition to 0, for success), to conform with the C/C++ standard. Linux Errno Example Macro: int EAFNOSUPPORT The address family specified for a socket is not supported; it is inconsistent with the protocol being used on the socket. ELIBBAD0.384Accessing a corrupted shared lib.80Accessing a corrupted shared library84Accessing a corrupted shared lib. http://unix.stackexchange.com/questions/8355/understand-error-codes-in-linux For instance, many implementations of grep use an exit status of 2 to indicate an error, and use an exit status of 1 to mean that no selected lines were found.
Macro: int ECONNRESET A network connection was closed for reasons outside the control of the local host, such as by the remote machine rebooting or an unrecoverable protocol violation. Enosys Error For example, if you try to delete a file that is the root of a currently mounted filesystem, you get this error. Macro: int ESPIPE Invalid seek operation (such as on a pipe). In brief, termination due to an uncaught signal results in exit status 128+[
Consider it a special case of incorrect usage. https://www.gnu.org/software/libc/manual/html_node/Error-Codes.html You get this error when you try to transmit data over a socket, without first specifying a destination for the data. Linux Error Codes List Exit Codes With Special MeaningsTable E-1. Posix Error Codes See Connecting.
Value for exit status 4 Detecting meaning of system() function's return value in Linux 5 Java processbuilder exitvalues 2 Confirm existance of executable (script, bat, cmd, exe) via a ruby file http://vbview.net/error-codes/oracle-exp-error-codes.php Macro: int ENOTBLK A file that isn’t a block special file was given in a situation that requires one. Takagi looked like? For a connectionless socket (for datagram protocols, such as UDP), you get EDESTADDRREQ instead. Linux Errno To String
About the 11 error code, it's indeed the segmentation fault number, mostly meaning that the program accessed a memory location that was not assigned. This often indicates a cycle of symbolic links. All rights reserved. (A whole bunch of text left out.) #define EX_OK 0 /* successful termination */ #define EX__BASE 64 /* base value for error messages */ #define EX_USAGE 64 /* weblink Macro: int EPROCUNAVAIL ???
On GNU/Hurd systems, this error never happens; you get a signal instead. Ebadf They are recorded in:- /usr/include/asm/errno.h Here is a copy of that file as of Aug 2004 on RedHat 7.3 #define EPERM 1 /* Operation not permitted */ #define ENOENT 2 /* Why did Ponda Baba and Doctor Evazan in the cantina dislike Luke so much?
ELIBMAX0.386Attempting to link in too many libs.82Attempting to link in too many shared libraries86Attempting to link in too many libs. Ending a script with exit 127 would certainly cause confusion when troubleshooting (is the error code a "command not found" or a user-defined one?). Typically, this error occurs when you are trying to delete a directory. Errno.h In C I will be posting instruction guides, how-to, troubleshooting tips and tricks on Linux, database, hardware, security and web.
Would Voldemort have succeeded if he simply ignored the prophecy? Why didn't Hans Gruber know what Mr. Macro: int EINTR Interrupted function call; an asynchronous signal occurred and prevented completion of the call. This system call facilitates passing the exit status code back to the parent, which can retrieve this value using the wait system call.
This happens not only when you use link (see Hard Links) but also when you rename a file with rename (see Renaming Files). Traditionally, the shell only stores an 8-bit return code, but sets the high bit if the process was abnormally terminated. $ sh -c 'exit 42'; echo $? 42 $ sh -c Some of these error codes can’t occur on GNU systems, but they can occur using the GNU C Library on other systems. How to serve your dragon?
Trying the same operation again will block until some external condition makes it possible to read, write, or connect (whatever the operation). Microwaving a glass of water, what happens?
