+// 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;
+
+
+// FUNCTION PROTOTYPES
+
+// ANSI standard strerror() function as described by ANSI chap. 7.11.6.2.
+// This is normally provided by <string.h>
+
+externC char *
+strerror( Cyg_ErrNo );
+
+// prototype for the actual implementation. Equivalent to the above, but
+// used internally by this product in preference
+
+externC char *
+_strerror( 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.
