+/**
+ * pr29_strerror - return string describing pr29 error code
+ * @rc: an #Pr29_rc return code.
+ *
+ * Convert a return code integer to a text string.  This string can be
+ * used to output a diagnostic message to the user.
+ *
+ * PR29_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.
+ * PR29_PROBLEM: A problem sequence was encountered.
+ * PR29_STRINGPREP_ERROR: The character set conversion failed (only
+ *   for pr29_8() and pr29_8z()).
+ *
+ * Return value: Returns a pointer to a statically allocated string
+ *   containing a description of the error with the return code @rc.
