	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.

isc_result_t isc_parse_uint8	(	isc_uint8_t *	uip,
		const char *	string,
		int	base
	)

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:

• 'string' points to a null-terminated string
• 0 <= 'base' <= 36

Returns:

• ISC_R_SUCCESS
• ISC_R_BADNUMBER The string is not numeric (in the given base)
• ISC_R_RANGE The number is not representable as the requested type.
