Posix File System Error Codes


Macro: int EPIPE Broken pipe; there is no process reading from the other end of a pipe. On these platforms, this function will raise an exception.Note: calls utimensat or lutimes.Since: :: FilePath -> IO () Source #touchFile path sets the access and modification times associated with file Macro: int ENETUNREACH A socket operation failed because the subnet containing the remote host was unreachable. This error happens on operations that are supposed to manipulate child processes, when there aren’t any processes to manipulate. his comment is here

Do not do this. Issue 6 The following new requirements on POSIX implementations derive from alignment with the Single UNIX Specification: The majority of the error conditions previously marked as extensions are now mandatory, except 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 /* strtol("0xfffffffff",NULL,0) on systems with a 32-bit wide long EILSEQ (Required since 1994 Amendment 1 to C89 standard)[3] Results from an illegal byte sequence, e.g. http://www-numi.fnal.gov/offline_software/srt_public_context/WebDocs/Errors/unix_system_errors.html

Linux Kernel Error Codes

In next execution, it throws an error number 17, which is "File already exist". Macro: int ETOOMANYREFS ??? errno is defined by the ISO C standard to be a modifiable lvalue of type int, and must not be explicitly declared; errno may be a macro. All the error names specified by POSIX.1 must have distinct values, with the exception of EAGAIN and EWOULDBLOCK, which may be the same.

mode will normally be either blockSpecialMode or characterSpecialMode. Table 6.1 OS Errors for Linux and other Unix-Like Systems Error code Value Description EPERM 1 Operation not permitted ENOENT 2 No such file or directory ESRCH 3 No such process EINTR 4 Note that any number of linked channels count as just one file opening; see Linked Channels. Linux Errno To String This condition never arises on GNU/Hurd systems.

This is used by the file locking facilities; see File Locks. ERROR_BAD_NETPATH 53 The network path was not found. Bash 101 Hacks eBook Sed and Awk 101 Hacks eBook Vim 101 Hacks eBook Nagios Core 3 eBook Copyright © 2008–2015 Ramesh Natarajan. http://www.thegeekstuff.com/2010/10/linux-error-codes The following C code snippet tries to open a file through open system call.

If mysqlbackup fails, because an operating system call fails, mysqlbackup usually displays the operating systems error code along with a detailed error message. Errno 0 ELIBSCN0.385.lib section in a.out corrupted.81.lib section in a.out corrupted85.lib section in a.out corrupted. Macro: int ENOMEM No memory available. POSIX compliant operating systems like AIX, Linux or Solaris include many other error values, many of which are used much more often than the above ones, such as EACCES for when

Posix Error Codes

Modes set by this operation are subtracted from files and directories upon creation. https://en.wikipedia.org/wiki/Errno.h Macro: int EBACKGROUND On GNU/Hurd systems, servers supporting the term protocol return this error for certain operations when the caller is not in the foreground process group of the terminal. Linux Kernel Error Codes Macro: int EAUTH ??? Errno.h In C See Connecting.

My focus is to write articles that will either teach you or help you resolve a problem. http://ismymailsecure.com/error-codes/pos-error-codes.html Macro: int ESTALE Stale file handle. In C programming language, there is an external variable called "errno". Macro: int ENAMETOOLONG Filename too long (longer than PATH_MAX; see Limits for Files) or host name too long (in gethostname or sethostname; see Host Identification). Errno.h Linux Kernel

mbstowcs(buf,"\xff", 1) on systems that use UTF-8. Macro: int EINVAL Invalid argument. Link Felix Frank October 21, 2010, 8:16 am Hi, good thinking, but this article desperately lacks a reference to perror. http://ismymailsecure.com/error-codes/posix-socket-error-codes.html See Socket Options.

Macro: int ENOENT No such file or directory. Ebadf Most functions indicate that they detected an error by returning a special value, typically NULL for functions that return pointers, and −1 for functions that return integers. O_CREAT flag is to create a file, if the file does not exist.

ERROR_TOO_MANY_OPEN_FILES 4 The system cannot open the file.

This change is for alignment with the ISO/IEC9899:1999 standard. The strerror function returns a string describing the error code passed in the argument errnum. See Socket Addresses. Efault Valid error numbers are all nonzero; errno is never set to zero by any system call or library function.

Macro: int EBUSY Resource busy; a system resource that can’t be shared is already in use. ELIBEXEC0.387Attempting to exec a shared library.83Cannot exec a shared library directly87Attempting to exec a shared library. Bibliography[edit] W. http://ismymailsecure.com/error-codes/posix-standard-error-codes.html This condition is detected by the exec functions; see Executing a File.

Macro: int ELOOP Too many levels of symbolic links were encountered in looking up a file name. Library functions store only values greater than zero. May fail with throwErrnoPathIfMinus1_ if a file named name already exists or if the effective user ID of the current process doesn't have permission to create the file.Note: calls mknod.Hard They are not yet documented.

Inside a C program, when a function fails, you should handle the errors accordingly, or at least record the errors in a log file. This happens not only when you use link (see Hard Links) but also when you rename a file with rename (see Renaming Files). Macro: int EREMOTE An attempt was made to NFS-mount a remote file system with a file name that already specifies an NFS-mounted file. (This is an error on some operating systems, In GNU, this error is always synonymous with ENOMEM; you may get one or the other from network operations.

Any conflict between the requirements described here and the ISOC standard is unintentional. On GNU/Hurd systems, this error never happens; you get a signal instead. To make your program portable, you should check for both codes and treat them the same. EINVAL Invalid argument (POSIX.1) EIO Input/output error (POSIX.1) EISCONN Socket is connected (POSIX.1) EISDIR Is a directory (POSIX.1) EISNAM Is a named type file EKEYEXPIRED Key has expired EKEYREJECTED Key was

The macro EWOULDBLOCK is another name for EAGAIN; they are always the same in the GNU C Library. For functions that operate on some object given in a parameter, such as a file descriptor or a port, it might instead mean that only that specific object (file descriptor, port, Macro: int EISDIR File is a directory; you cannot open a directory for writing, or create or remove hard links to it. Addison-Wesley Professional.

On these platforms, this function will raise an exception.Note: calls lutimes.Since: file sizessetFileSize :: FilePath -> FileOffset -> IO () Source #Truncates the file down to the specified length. Any library function can alter the value stored before return, whether or not they detect errors. The header file also defines macros that expand to integer constants that represent the error codes. For details of in-depth Linux/UNIX system programming training courses that I teach, look here.

Macro: int EACCES Permission denied; the file permissions do not allow the attempted operation.
