Eintr Error Number


Once signals are blocked, the flags set by the handlers can be checked and pselect is called which unblocks the signals is an atomic manner. for the devices. Macro: int EPIPE Broken pipe; there is no process reading from the other end of a pipe. This error is never generated by GNU/Hurd systems, but it can result from an operation to an NFS server running another operating system. http://dssoundware.com/error-codes/eintr-error-4.php

I'll mention it in the article. All rights reserved. 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 Most system headers contain at least this much information for the standard errno values, so don't be afraid to take a look. http://www.gnu.org/s/libc/manual/html_node/Error-Codes.html

Linux Kernel Error Codes

This article familiarizes you with UNIX error reporting in the standard C library and (hopefully) encourages you to report and handle errors in a user-friendly way.Let's dig in!Back to topBefore you However, the execution was blocked inside ZeroMQ's recv function which never returned back to the Python runtime and thus the termination never happened. I'm using HANDLE_EINTR and HANDLE_EAGAIN macros (grabbed from Chrome source code). –Efstathios Chatzikyriakidis Sep 8 '14 at 18:11 Any other ideas? Note that any number of linked channels count as just one file opening; see Linked Channels.

Notify administrators if there is objectionable content in this page. For instance ENOFILE, means you tried to access a file that doesn't exist, etc. 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. Eintr Linux Macro: int EUSERS The file quota system is confused because there are too many users.

This trick is even applicable in libraries.

Valid error numbers are all nonzero; errno is never set to zero by any system call or library function.

Posix Error Codes

If you see somebody checking EINTR on, say, seteuid() then the programmer is nuts. –John Hascall Sep 8 '14 at 19:27 | show 3 more comments Did you find this question This error can happen in a few different situations: An operation that would block was attempted on an object that has non-blocking mode selected. Linux Kernel Error Codes But I think that some of these or even all may return EINTR because they may use inner modules or calls that may fail with EINTR and back propagate that error.

Signal handlers are set by the main module and should not be changed randomly in the background by the libraries.

We appreciate your feedback. 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 No more space for writing is available on the device (for example, when the disk is full).ERANGEResult too large.

Some of the values in ERRNO.H are present to maintain compatibility with the UNIX family of operating systems.The errno values in a 32-bit Windows operating system are a subset of the To understand the rationale behind EINTR, let's do a little coding exercise. Macro: int EAGAIN Resource temporarily unavailable; the call might work if you try again later. Listing 3 shows you how to use this thread-safe version.Listing 3.
