Function Documentation

xstrtoui()

bool xstrtoui	(	const char *	s,
		char **	end,
		unsigned int *	value,
		unsigned int	min,
		unsigned int	max
	)

Convert a c-string (or its prefix) into an unsigned integer.

Parameters

s	input string
end	like strtoul's "end" pointer
value	pointer for result. Undefined on failure
min	minimum accepted value
max	maximum accepted value

If @end is nullptr, we assume the caller wants a "strict strtoul", and hence "15a" is rejected. In either case, the value obtained is compared for min-max compliance. Base is always 0, i.e. autodetect depending on @s.

Returns

true/false whether number was accepted. On failure, *value has undefined contents.
