// Author(s):    jlarmour
// Contributors: 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 ....

/* TYPE DEFINITIONS */

/* A type for error codes which may be useful to explain the purpose of
 * a variable or return code. It shows that it contains an error code
 * of the type defined below */

typedef int Cyg_ErrNo;


/* CONSTANT DEFINITIONS */

/* If adding to this list, you must also update strerror() with its text
 * If there is a common error of the same purpose on Unix, try and use its
 * name and number. If not, use one above 200 to prevent future conflicts
 *
 * Do not use negative numbers, so that functions can return positive on
 * success and -ESOMETHING on error, and it all works consistently.
