* HISTORY
|
|
* 04-Mar-85 Rudy Nedved (ern) at Carnegie-Mellon University
|
|
* Create a CMU version of the BBN errmsg routine from scratch. It
|
|
* differs from the BBN errmsg routine in the fact that it uses a
|
|
* negative value to indicate using the current errno value...the
|
|
* BBN uses a negative OR zero value.
