Errno 25 is usually generated when a program tries to execute an
ioctl command that expects the file descriptor to be a terminal.
(ie: you can't set the baud rate on a file).
However I have also noticed that some aplications aren't very
carefull when they use errno. For example, Informix may give
you this message if it cannot open a database file because it
does not exist!
I think there may be one or two system calls that will alter
errno to be 25, without returning a non-zero value, when in
fact there was no error.
