Eintr Error Code Value

Contents

The dictionary errno.errorcode maps numeric codes to symbol names, e.g., errno.errorcode[2] could be the string 'ENOENT'. Forum Today's Posts C and C++ FAQ Forum Actions Mark Forums Read Quick Links View Forum Leaders What's New? Below is a list of the symbolic error names that are defined on Linux. ELIBEXEC0.387Attempting to exec a shared library.83Cannot exec a shared library directly87Attempting to exec a shared library. http://csimonitoring.com/error-code/eintr-error-code.php

Macro: int EALREADY An operation is already in progress on an object that has non-blocking mode selected. Trees Indices Help Python Standard Library Moduleerrno [hideprivate] [frames]|noframes] Module errno This module makes available standard errno system symbols. rename can cause this error if the file being renamed already has as many links as it can take (see Renaming Files). To handle Ctrl+C in a custom way we have to implement a signal handler: volatile int stop = 0; void handler (int) { stop = 1; } void event_loop (int sock) http://www.gnu.org/s/libc/manual/html_node/Error-Codes.html

Linux Kernel Error Codes

Symbols that are not relevant to the underlying system are not defined. Macro: int EAUTH ??? If signals are blocked, and a signal happens, it is queued, not discarded. Second, even some POSIX blocking functions don't return EINTR in case of a signal.

This often indicates a cycle of symbolic links. invalid for this operation EREMCHG0.382Remote address changed78Remote address changed82Remote address changed ELIBACC0.383Can't access a needed shared lib.79Can not access a needed shared library83Can't access a needed shared lib.

In the tight event loop it would work OK. After some investigation, it turned out that Python runtime works more or less like the examples above. The perror function is infinitely useful when dealing with errno (but sadly renders the point of this huge table mute). additional hints This error happens on operations that are supposed to manipulate child processes, when there aren’t any processes to manipulate.

Macro: int ENEEDAUTH ??? Eintr Signal I don't understand EINTR means and I also cannot find its definition in my whole program packet. You can also simply drop me a line to say hello!. View and manage file attachments for this page.

Posix Error Codes

Macro: int ERANGE Range error; used by mathematical functions when the result value is not representable because of overflow or underflow. over here block signals 2.

My assumption is that blocking functions cannot be combined with Ctrl+C and with decent clean-up on Windows. his comment is here pthread_mutex_lock is not often a problem as it is generally not used to block for arbitrary amount of time. Macro: int EPROCLIM This means that the per-user limit on new process would be exceeded by an attempted fork. Macro: int EMLINK Too many links; the link count of a single file would become too large. Eintr Errno

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.

Some are defined by POSIX, and some are additional values. Eintr Select Find out what you can do. All of them expand into integer constant values.

However, on (very) old UNIX systems, there may be no and the declaration is needed.

In this blog post I'll try to explain what EINTR is good for and how to handle it in your code. Macro: int ECHILD There are no child processes. For example, trying to mount an ordinary file as a file system in Unix gives this error. C Programming Error Codes Reply Options Unfold by martin_sustrik, 11 Nov 2014 16:07 Fold Iurie Solomon (guest) 28 Mar 2016 17:21 in alternative, u can use the fcntl (filedes, F_SETFL, new_flags) with the O_NONBLOCK macro:

Macro: int ENOTEMPTY Directory not empty, where an empty directory was expected. Macro: int ESRCH No process matches the specified process ID. This can mean that the function does not implement a particular command or option value or flag bit at all. navigate here Finally there are few fine points to be aware of: First, there's no EINTR on Windows.

EBADFBad file number. perror function : We need to pass some string . Macro: int ENOLCK No locks available. Column 2 is a score that indicates the fraction of platforms on which the identifier is found (1 meaning all).

Then a test of this global flag followed by a call of select() could hang indefinitely if the signal arrived just after the test but just before the call. Note: In QNX Neutrino 6.4.0, EALREADY was defined as EALREADY_OLD; in QNX Neutrino 6.6.0, it's defined as EALREADY_NEW. Some of these are marked POSIX.1, indicating that the name is defined by POSIX.1-2001, or C99, indicating that the name is defined by C99. else unblock signals and return data to user It can never happen that a signal is received and we wait indefinitely in pselect().

You have to include errno.h header file to use external variable errno. Macro: int EDESTADDRREQ No default destination address was set for the socket. What you can do is resort to having a thread waiting for events on a pipe written to by the signal handler (see above!) then have that thread signal/broadcast on you errno is thread-local; setting it in one thread does not affect its value in any other thread.

In such cases, a successful return can be distinguished from an error return by setting errno to zero before the call, and then, if the call returns a status that indicates paper out ESHLIBVERS0.187Shared library version mismatch EBADEXEC0.185Bad executable EBADARCH0.186Bad CPU type in executable -0.143Unknown error UNKNOWN0.137Unknown error [1] AIX ENOTEMPTY is 17 "Directory not empty" if _ALL_SOURCE and !_LINUX_SOURCE_COMPAT [2] AIX Macro: int ENETRESET A network connection was reset because the remote host crashed.

Dev centers Windows Office Visual Studio Microsoft Azure More... Macro: int ENOTDIR A file that isn’t a directory was specified when a directory is required. However, not all the definitions given in ERRNO.H are used in 32-bit Windows operating systems. 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).

If Ctrl+C is pressed while the event loop is blocked in recv, you'll get a kind of deadlock: Signal handler is executed as expected, it sets 'stop' to 1, but then Macro: int ENOBUFS The kernel’s buffers for I/O operations are all in use. Macro: int EISDIR File is a directory; you cannot open a directory for writing, or create or remove hard links to it.
