+ * Do an operating system operation
+ * This is an example of a function which performs some sort of operating
+ * system operation, returning an errno-like indication of its success or
+ * failure.  We'd like the documentation to list all the possible failure
+ * indications that this function can return, which is only a tiny subset of
+ * all the possible errno values.  Hence, we don't define it as returning an
+ * enum of some sort, since that would cause c2man to list every possible value
+ * that type can have.
+ * Returns an indication of success or failure, as follows:
+ *	EOK: Success
+ *	EIO: I/O error
+ *	ENOMEM: Out of memory
+ *	EIEIO: Old Macdonald error
