staticnoexcept

Compares substrings of two specified string objects and returns an integer that indicates their relative position in the sort order.

Parameters

str_a	The first string to use in the comparison.
index_a	The position of the substring within str_a.
str_b	The second string to use in the comparison.
index_b	The position of the substring within str_b.
length	The maximum number of characters in the substrings to compare

Returns

A 32-bit signed integer that indicates the lexical relationship between the two compares.

Value	Condition
Less than zero	str_a precedes str_b in the sort order.
