Umm... huh?  This question makes no sense at all.  Do you want to know
how to _use_ errno?  It's real simple:  once any i/o function has
failed, you can test errno to determine what the error that occurred
was.  <errno.h> defines the standard error codes as macros, and you can
use the 'perror()' library function to automatically print an error
message based on the contents of errno.  RTFM.

Please ask more specific questions.
