+/*%<
+ * Parse the null-terminated string 'string' containing a base 'base'
+ * integer, storing the result in '*uip'.
+ * The base is interpreted
+ * as in strtoul().  Unlike strtoul(), leading whitespace, minus or
+ * plus signs are not accepted, and all errors (including overflow)
+ * are reported uniformly through the return value.
+ *
+ * Requires:
+ *\li	'string' points to a null-terminated string
+ *\li	0 <= 'base' <= 36
+ *
+ * Returns:
+ *\li	#ISC_R_SUCCESS
+ *\li	#ISC_R_BADNUMBER   The string is not numeric (in the given base)
+ *\li	#ISC_R_RANGE	  The number is not representable as the requested type.
