But... Are assignments in the condition part of conditionals a bad practice? name not unique EBADFD0.381f.d. You can't even depend on that being the actual Unix error, but even if it is, what does it mean?

Unfortunately, those files are only a little bit more illuminating than the numeric errors themselves. http://www.unixmantra.com/2014/04/linux-aix-os-return-codes.html Is it dangerous to use default router admin passwords if only trusted users are allowed on the network? Linux Errno Codes So, the thing to keep in mind is that just because you've seen a particular error on a particular platform doesn't mean it is the same somewhere else. Linux Errno Example Well, every Unix/Linux system includes various ".h" files that describe the numeric errors returned by kernel system calls.

If you try to specify SIGKILL or SIGSTOP to sigaction(), you'll get this return. share|improve this answer answered May 20 '09 at 8:32 JesperE 43.6k10103164 I checked the errno with another code I wrote, this a simple version of that one.

Does anyone know what this error code means, or how i might be able to work around this (fnctl maybe??). To understand the nature of the error these codes need to be interpreted. In C programming language, there is an external variable called "errno". this contact form In order to become a pilot, should an individual have an above average mathematical ability?
