In GNU, this error is always synonymous with ENOMEM; you may get one or the other from network operations. I'm going to be working in Eclipse using the C/C++ Development Tooling (CDT). The system tried to use the device represented by a file you specified, and it couldn’t find the device. This error happens on operations that are supposed to manipulate child processes, when there aren’t any processes to manipulate.

Each thread in a multi-threaded program has its own error value in its thread local storage. All information submitted is secure. Macro: int EISCONN You tried to connect a socket that is already connected.

This is generally around 2GB, but most modern file systems support much larger files, sometimes requiring 64-bit versions of the read()/write() and lseek() functions.EINTR -- The function was interrupted by a A description of the project, information about reporting bugs, and the latest version of this page, can be found at https://www.kernel.org/doc/man-pages/. 2016-03-15 ERRNO(3) Copyright and license for this manual page HTML Macro: int EACCES Permission denied; the file permissions do not allow the attempted operation. Linux Errno To String man sem_open suggests this errno means sem_open() is not supported by system. #define ENOSYS 38 /* Function not implemented */ The sem_open() userspace is in librt which we link against dynamically

The affected system claims to support POSIX semaphores: _POSIX_SEMAPHORES is true and sysconf(_SC_SEMAPHORES) confirms this. Posix Error Codes I think /dev/shm is necessary too but sem_open() is failing before that, and strace supports this. # /* Quick'n'dirty test program to illustrate sem_open failure #Run this file to auto-build test 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. Which news about the second Higgs mode (or the mysterious particle) anticipated to be seen at LHC around 750 GeV?

Macro: int EDESTADDRREQ No default destination address was set for the socket. Enxio This indicates that the function called is not implemented at all, either in the C library itself or in the operating system. It will not work with modern versions of the C library. In order to support a safe transition to the new value, you should modify your code as follows: If your code checks for EALREADY return codes, recode it to be like

My adviser wants to use my code for a spin-off, but I want to use it for my own company Invariants of higher genus curves Rot and polyalphabetic ciphers in Python Eintr Signal This happens not only when you use link (see Hard Links) but also when you rename a file with rename (see Renaming Files). Why can't QEMU allocate the memory if the Linux caches are too big?

All the error names specified by POSIX.1 must have distinct values, with the exception of EAGAIN and EWOULDBLOCK, which may be the same.

Some functions that must always block (such as connect; see Connecting) never return EAGAIN. Systems with issue are Slackware 10.1.0 kernel 2.6.11 /lib/librt-2.3.4.so /lib/libpthread-0.10.so, but the same code works on the much older RedHat 9 kernel 2.4.20 /lib/librt-2.3.2.so /lib/tls/libpthread-0.29.so.
