LKBEN11077: Posix error 14: Bad address

Symptom

You get the error message: Bad address

Cause

none

Solution

In C/C++ or Objective C programming an EFAULT is a bad buffer address... are you sure you've actually initialized this buffer to point to something valid? It's obviously a global or sometime... which itself is a pretty bad idea. You should allocate it in your function or it should be an ivar (if you're using Obj-C).

The POSIX error code 14 is called EFAULT, and it means you made a system call with an invalid pointer value. This is almost certainly some user-supplied buffer pointer to a read or write system call of some sort. Check all of the buffer pointers and make sure they're not NULL. Check the return value from malloc() - you might be failing to allocate a buffer.

Check on the file under /usr/include/asm/errno.h that contains a complete list of basic error codes.

# cat /usr/include/bits/errno.h
# cat /usr/include/asm-generic/errno.h

Bad address; an invalid pointer was detected. In the GNU system, this error never happens; you get a signal instead.

Shell Programming

ERROR IS "cat: write error: Bad address."

PS:
The Postfix "bad address syntax" has nothing to do with the EFAULT bad address!
