// Author(s):    jlarmour

// Date:         2000-04-14
// Purpose:      To provide a common set of error codes
// Description:  This provides a common set of error codes that all
//               packages can agree on. It doesn't preclude them defining
//               their own error return system, but this is a preferable
//               system to use to help error support be as general as
//               possible.
//
//               We try and conform to the ANSI/POSIX error code format,
//               namely starting with the character 'E'
//
// Usage:        #include <cyg/error/codes.h>
//
//               Example:
//
//               err=myfun();
//               if (err != ENOERR)
//               {
//                 str=strerror(err);
//                 printf("myfun returned error: %s\n", str);
//               }
//               else ....
