Eintr Error Code


rename can cause this error if the file being renamed already has as many links as it can take (see Renaming Files). Also, fcntl return EINTR in case of locking but I dont care for it. –Efstathios Chatzikyriakidis Sep 8 '14 at 18:21 | show 9 more comments Your Answer draft saved POSIX specifies one approach: make the primitive fail right away. for the devices. this contact form

However, be sure to set both ends of the pipe to non-blocking. Train and bus costs in Switzerland Wrong password - number of retries - what's a good number to allow? Why doesn't Rey sell BB8? 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 http://www.gnu.org/s/libc/manual/html_node/Error-Codes.html

Photoshop's color replacement tool changes to grey (instead of white) — how can I change a grey background to pure white? Then restart the blocking function. Macro: int ENETRESET A network connection was reset because the remote host crashed. Macro: int EXDEV An attempt to make an improper link across file systems was detected.

You can step through each function in turn and check whether EINTR or EAGAIN is a valid error code. Macro: int EHOSTUNREACH The remote host for a requested network connection is not reachable. Macro: int ENOMEM No memory available. Eintr Signal students who have girlfriends/are married/don't come in weekends...?

For a connectionless socket (for datagram protocols, such as UDP), you get EDESTADDRREQ instead. And let's pretend there's no EINTR and recv just continues waiting for data whatever happens: void event_loop (int sock) { while (1) { char buf [1]; recv (sock, buf, 1, 0); Join them; it only takes a minute: Sign up Which system calls can return EINTR or EAGAIN error codes?

Linux Errno Example 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. You can use the select function to find out when the pending operation has completed; see Waiting for I/O. Does every DFA contain a loop?

Eintr Errno

Python's signal handler handled the signal by marking down that the process should be terminated as soon as possible. http://man7.org/linux/man-pages/man3/errno.3.html It manages limited memory so well that hundreds of processes can share the system efficiently, and expertly organizes data transfers so that the CPU isn't kept waiting any longer than necessary Linux Kernel Error Codes Macro: int ESPIPE Invalid seek operation (such as on a pipe). Eintr Select Should I handle EINTR for the calls or the SA_RESTART is enough? –Efstathios Chatzikyriakidis Sep 8 '14 at 18:35 add a comment| up vote 1 down vote There is a section

Otherwise the signal handler could block if the pipe buffer fills up and the program would deadlock. Eintr Linux

Yes, you are right. If the value of errno should be preserved across a library call, it must be saved: if (somecall() == -1) { int errsv = errno; printf("somecall() failed\n"); if (errsv == ...) My assumption is that blocking functions cannot be combined with Ctrl+C and with decent clean-up on Windows. http://dssoundware.com/error-code/e50-error-code.php In this blog post I'll try to explain what EINTR is good for and how to handle it in your code.

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, Posix Error Codes You get this error when you try to transmit data over a socket, without first specifying a destination for the data. Mutexes are normally locked only for a very short time until some simple atomic operation is performed.

User of the library can use this function to handle signals in a race-free way.

Unfortunately, that's not the case for libraries. Macro: int ENOLCK No locks available. As long as I don't have a signal handler, I have not care about. –stefangachter Feb 11 '11 at 7:32 2 @stefangachter As you concluded, It's important to notice that C Programming Error Codes share|improve this answer edited Dec 4 '15 at 13:51 Steve Lorimer 6,45063682 answered Feb 10 '11 at 16:49 ydroneaud 2,7481231 1 So, as long as I don't use signals in

For instance ENOFILE, means you tried to access a file that doesn't exist, etc. Reply Options Unfold by martin_sustrik, 07 Nov 2012 09:53 Fold Andrea (guest) 07 Nov 2012 09:47 Ok, I think I found the problem: it seems that if you install a signal However, the execution was blocked inside ZeroMQ's recv function which never returned back to the Python runtime and thus the termination never happened. his comment is here However, ZeroMQ library used to have a blocking recv function, that (oops!) haven't returned EINTR and rather ignored the signals.

The value returned by TEMP_FAILURE_RETRY is whatever value expression produced. Macro: int EACCES Permission denied; the file permissions do not allow the attempted operation. Macro: int EPROCUNAVAIL ??? Macro: int EWOULDBLOCK In the GNU C Library, this is another name for EAGAIN (above).

Let's do the Wave! The macro EWOULDBLOCK is another name for EAGAIN; they are always the same in the GNU C Library. C libraries in many older Unix systems have EWOULDBLOCK as a separate error code. Macro: int ENOSPC No space left on device; write operation on a file failed because the disk is full.

If you get EAGAIN when you didn't ask for it, there's a serious logic error either in your program or in the kernel. –tmyklebu Sep 8 '14 at 18:39 | show Macro: int EDQUOT The user’s disk quota was exceeded. The problem here is that you have to somehow force the blocking function to exit when signal happens. If anybody knew, please tell me.

If the entire function is not available at all in the implementation, it returns ENOSYS instead. I read a program it has : if (errno == EINTR) in that program , if this is true, it will continue... Sep 8 '14 at 18:21 So, you believe that I would not handle the EINTR from the referred system calls since the man page do not refer anything at Macro: int EIEIO Go home and have a glass of warm, dairy-fresh milk.
