Compares at most n characters of two possibly null-terminated arrays.
Compares at most count characters of two possibly null-terminated arrays. The comparison is done lexicographically.
The behavior is undefined when access occurs past the end of either array s1 or s2. The behavior is undefined when either s1 or s2 is the null pointer.
- Parameters
-
s1 pointers to the null-terminated byte strings to compare s2 pointers to the null-terminated byte strings to compare n maximum number of characters to compare
- Returns
- Negative value if s1 appears before s2 in lexicographical order. Zero if s1 and s2 compare equal, or if n is zero. Positive value if s1 appears after s2 in lexicographical order.
References n, NULL, r, s1, and s2.
