  1. Got something to add?
  2. Macro: int EILSEQ While decoding a multibyte character the function came along an invalid or an incomplete sequence of bytes or the given wide character is invalid.
  3. The perror function is infinitely useful when dealing with errno (but sadly renders the point of this huge table mute).
  4. For example, if a function returns an unsigned char value but calculated a result of 256 or more (or -1 or less), errno would be set to ERANGE and the function

BSD systems return this if you try to open a pty device that is already in use. How do I handle an unterminated wire behind my wall? There's also nothing that prevents a programmer from misusing these constants in their own error returns, either through ignorance or simple misunderstanding of the historical use of these. Check This Out Third party libraries often have a single convention that's followed by all of the functions in the library but, again, you'll have to check the library's documentation before making any assumptions.Let's

Macro: int ERANGE Range error; used by mathematical functions when the result value is not representable because of overflow or underflow. Errno.h Linux Kernel But... Repairing this condition usually requires unmounting, possibly repairing and remounting the file system.

Development of retrosynthesis plan Strange device identification What does this ice key do?

That's the purpose of this error, though it is also used for the pause() function and some IPC functions. #define EIO 5 /* I/O error */ The catchall for all manner Assumiong you aren't rrying to execute arbitrary data and haven't copied a binary from some other OS, you probably have a corrupt file. #define EBADF 9 /* Bad file number */ Macro: int EFTYPE Inappropriate file type or format.

Contact Site Map Numeric Unix Error Messages It's an unfortunate fact that many programmers are lazy about error messages. Or you can use: char *strerror(int errnum); to return the description of the error as a string so you can inspect it or print it how you like. They are supported on UNIX systems by other languages (C++, Objective-C, Python, and so forth). this contact form Every library function that returns this error code also generates a SIGPIPE signal; this signal terminates the program if not handled or blocked.

I have to investigate why they weren't defined in the main errno header Michael B Allen Copyright (c) Sat Feb 26 15:02:33 EST 2005 current community chat Unix You get this error when you try to transmit data over a socket, without first specifying a destination for the data. You can choose to have functions resume after a signal that is handled, rather than failing with EINTR; see Interrupted Primitives. Thus, your program will never actually see EPIPE unless it has handled or blocked SIGPIPE.
