//#####DESCRIPTIONBEGIN####
//
// 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 ....
//
