For example, attempting to remove a directory while another application is reading it. http://csimonitoring.com/error-codes/eintr-error.php
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). Under MS-DOS operating system versions 3.0 and later, EACCES may also indicate a locking or sharing violation. For example, accept() can block your process so it can be interrupted by a signal, but setsid() is so short that it has been written to not be interrupted by signals. EDIT: Ambroz Bizjak suggests to use pselect (and similar functions) to deal with the race condition above.
Linux Kernel Error Codes
Note that this is not the sort of deadlock you get in multithreaded code -- errno and its friends definitely can't help you track those down.EDOM -- The input argument is and .. I have the following system calls in C: access() unlink() setsockopt() fcntl() setsid() socket() bind() listen() I want to know if they may fail with error code -1 and errno EINTR/EAGAIN. Most system headers contain at least this much information for the standard errno values, so don't be afraid to take a look.
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. Cache coherence related questions are kind of out of scope of the article. In any case, I insist that listing2 and listing3 have no different behavior. Eintr Linux If you retry sending the packet, then it is sent TWICE, which may confuse the other end.
Otherwise , we can call the errstr function with current number values, it will also tell us error description , what we got . 02-23-2010 #7 Rede View Profile View Forum To access the actual operating system error code, use the _doserrno variable, which contains this value.The following errno values are supported: ECHILDNo spawned processes.EAGAINNo more processes. perror , strerror . find this The link in John's answer should be helpful answering questions about specific functions, though.
Some of these error codes can’t occur on GNU systems, but they can occur using the GNU C Library on other systems. Eintr Select Macro: int EMLINK Too many links; the link count of a single file would become too large. EDIT: Please note that to make blocking fuctions like recv return EINTR you may have to use sigaction() with SA_RESTART set to zero instead of signal() on some operating systems.

Macro: int ECONNABORTED A network connection was aborted locally. Has Tony Stark ever "gone commando" in the Iron Man suit? Linux Kernel Error Codes Despite the popularity of other languages on UNIX (such as Java™, C++, Python, or Perl), all of the application programming interfaces (APIs) of systems have been created for C. Linux Errno Example You've just added a check on the return value & errno, but if the recv call is exiting with EINTR, you should have exact the same behaviour in both listings regardless
The following error codes are defined by the Linux/i386 kernel. Did Umbridge hold prejudices towards muggle-borns before the fall of the Ministry? However, ZeroMQ library used to have a blocking recv function, that (oops!) haven't returned EINTR and rather ignored the signals. Your display name must be unique in the developerWorks community and should not be your email address for privacy reasons. Eintr Errno
This is the opposite of the EISDIR error.ENOTEMPTY -- The specified directory isn't empty, but it needs to be. Macro: int ENOTDIR A file that isn’t a directory was specified when a directory is required. Macro: int ENETDOWN A socket operation failed because the network was down. http://csimonitoring.com/error-codes/eintr-error-4.php Forgot your IBM ID?
The thread-safe strerror_r() function in action// Thread-safe usage of strerror_r(). Eintr Signal See Socket Addresses. If, for example, the main application already has a signalfd handling Ctrl+C signal, creating a new signalfd in the library causes the signal to be delivered alternatively to the main application
By default, you have the SA_RESTART behavior, so you don't have to worry about EINTR, if you don't play with signals.
This error means you got lucky and the system noticed; it might just hang. 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 Learn more.

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 Besides that, this doesn't seem to work anyway. navigate here Redistributions of source code must retain the above copyright * notice, this list of conditions and the following disclaimer. * 2.
For example, UNIX filesystems don't let you move a file between file systems (instead, you have to copy the file, then delete the original).One annoying feature of the POSIX 1003.1 specification This happens not only when you use link (see Hard Links) but also when you rename a file with rename (see Renaming Files). EINTR is considered only from 3rd listing on. For instance ENOFILE, means you tried to access a file that doesn't exist, etc.
No more file descriptors are available, so no more files can be opened.ENOENTNo such file or directory. Macro: int ED The experienced user will know what is wrong. not avail */ #define EPROGMISMATCH 75 /* Program version wrong */ #define EPROCUNAVAIL 76 /* Bad procedure for program */ #endif /* _POSIX_SOURCE */ #define ENOLCK 77 /* No locks available What happened was that user called ZeroMQ's recv function from Python, which started waiting for incoming data.
Many system calls refer to such things. Using -njo and -cxjo for family members 2048-like array shift Very simple number line with points Writing referee report: found major error, now what? Mutexes are normally locked only for a very short time until some simple atomic operation is performed. Additionally, If you are implementing a blocking function yourself, take care to return EINTR when you encounter a signal.
When you get this error, you can be sure that this particular function will always fail with ENOSYS unless you install a new version of the C library or the operating students who have girlfriends/are married/don't come in weekends...? Macro: int EHOSTUNREACH The remote host for a requested network connection is not reachable. Luckily, most functions will only have a few possible errors to report, so it's usually not that hard to handle them appropriately.Back to topDealing with errorsAdding error-handling code to your program
