How To Use Errno

Valid error numbers are all nonzero; errno is never set to zero by any system call or library function. Read More Here Its value is significant only when the return value of the call indicated an error (i.e., -1 from most system calls; -1 or NULL from most library functions); a function that Errno Values ENOEXEC Exec format error (POSIX.1) ENOKEY Required key not available ENOLCK No locks available (POSIX.1) ENOLINK Link has been severed (POSIX.1) ENOMEDIUM No medium found ENOMEM Not enough space (POSIX.1) ENOMSG Errno.h In C Some of these are marked POSIX.1, indicating that the name is defined by POSIX.1-2001, or C99, indicating that the name is defined by C99.

However: Errno have their values hard-coded, which is incorrect (higher numbered codes may [do!] differ per platform). http://ismymailsecure.com/posix-error/posix-error-13.html All the error names specified by POSIX.1 must have distinct values, with the exception of EAGAIN and EWOULDBLOCK, which may be the same. It will not work with modern versions of the C library. GNU Project. 2014-02-08. Errno C++

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 == ...) POSIX compliant operating systems like AIX, Linux or Solaris include many other error values, many of which are used much more often than the above ones, such as EACCES for when Issue 5 Updated for alignment with the POSIX Realtime Extension. http://ismymailsecure.com/posix-error/posix-error-51.html Retrieved 2015-05-08. ^ Stevens & Rago 2013, p.14.

Most functions indicate that they detected an error by returning a special value, typically NULL for functions that return pointers, and −1 for functions that return integers. Errno To String Retrieved 27 February 2015. ISBN978-0321637734.

Any library function can alter the value stored before return, whether or not they detect errors.

In general, the SAS/C Library will issue diagnostics for failures of USS functionality only when (a) the failure is certainly the result of programmer error, or (b) the error is so Strerror Example Also refer to errno.h for socket-related errno values.

However, on (very) old UNIX systems, there may be no and the declaration is needed. errno is thread-local; setting it in one thread does not affect its value in any other thread. Below is a list of the symbolic error names that are defined on Linux. http://ismymailsecure.com/posix-error/posix-error-ios-7.html 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
