Eintr Error Code Value

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 For example, trying to mount an ordinary file as a file system in Unix gives this error. thank u!

On the other hand, if you get Ctrl+C while you're not in pselect(), the signal handler will not run until you call pselect() (because signals are blocked), and when you finally See File Locks, for an example.

See pages that link to and include this page. For starters, the period between the check and the recv is extremely short and it is thus very unlikely that the signal handler gets executed precisely at that point. You can use select to find out when the operation will be possible; see Waiting for I/O. Specifically, this is the case for pthread_cond_wait and pthread_mutex_lock.

Linux Kernel Error Codes The values are always the same, on every operating system. Linux Errno Example Under MS-DOS operating system versions 3.0 and later, EACCES may also indicate a locking or sharing violation.

It is probably a good idea to delay for a few seconds before trying it again, to allow time for other processes to release scarce resources. weblink In the tight event loop it would work OK. EALREADY_NEW The new value (237). Macro: int ENOLCK No locks available. Eintr Errno

The documentation for a function might list special meanings for certain values of errno, but this doesn't mean that these are necessarily the only values that the function might set. No more file descriptors are available, so no more files can be opened.ENOENTNo such file or directory. 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 navigate here Macro: int ENFILE There are too many distinct file openings in the entire system.

That allows the event loop to wrap over and check the 'stop' variable: volatile int stop = 0; void handler (int) { stop = 1; } void event_loop (int sock) { Eintr Select it's fork()'s error. My suggestion would be to use sem_wait (which returns EINTR) instead of pthread_cond_wait.

Still, it doesn't work for libraries.

Users do not usually see this error because functions such as read and write translate it into a SIGTTIN or SIGTTOU signal. The event loop is stuck in recv and has no opportunity to check whether 'stop' was set to 1. C Programming Error Codes Macro: int EPROGUNAVAIL ???

This is a “file doesn’t exist” error for ordinary files that are referenced in contexts where they are expected to already exist. Read more about Ramesh Natarajan and the blog.

Register Remember Me? The value of each symbol is the corresponding integer value, e.g., on most systems, errno.ENOENT equals the integer 2. Is there any guarantee that you cannot get EINTR if the packet has been transmitted?

Macro: int ENOTCONN The socket is not connected to anything. On GNU/Hurd systems, this error never happens; you get a signal instead. You have to include errno.h header file to use external variable errno.

This article might be a handy reference for you, when you encounter an error number and you would like to know what it means. For example, if you try to delete a file that is the root of a currently mounted filesystem, you get this error. 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. In any case, I insist that listing2 and listing3 have no different behavior.

So there is one errno for each thread. This error signifies that an attempt was made to access a file (or, in some cases, a directory) in a way that is incompatible with the file's attributes.For example, the error
