/*%<
* 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.
