It is an error code thrown from the c functions like lseek or write. It means 'Bad file descriptor' - typically occurs when a program cannot write to the file for any of the following reasons: Growing beyond ulimit, writing to a read-only file (either opened as read only or permission issues), or has been closed externally (such as losing a network drive).
As a general rule of thumb, if you see errno, it is a C level error, so you can check out error codes for seemingly similar C functions. Obviously, this error condition is something that can be better documented or trapped though.

Where would one find what error 9 means exactly? I scanned the documentation and didn't see any mention of an error 9 for WRITESEQ or even described in STATUS() which is where a lot of the IO errors show up.
