* Convert a return code integer to a text string. This string can be

*
|
|
* PUNYCODE_SUCCESS: Successful operation. This value is guaranteed

* to always be zero, the remaining ones are only guaranteed to hold

* non-zero values, for logical comparison purposes.
|
|
* PUNYCODE_BAD_INPUT: Input is invalid.
|
|
* PUNYCODE_BIG_OUTPUT: Output would exceed the space provided.
|
|
* PUNYCODE_OVERFLOW: Input needs wider integers to process.
|
|
*
|
|
* Return value: Returns a pointer to a statically allocated string
|
|
* containing a description of the error with the return code @rc.
