Error Message Library

Many of the packages in CODA return a status value which indicates success or failure, and if not successful, it indicates what the problem was. C header files exist for testing for specific error returns from each package or facility. Generally, though, it is sufficient to note that an operation failed, and to report the error to the user. The routines in this library can either print the error message corresponding to the error code, or return the character string to the user for further formatting.
