Compares two null-terminated byte strings lexicographically.
Compares two null-terminated byte strings lexicographically.
The behavior is undefined if s1 or s2 are not pointers to null-terminated byte strings.
- Parameters
-
s1 pointers to the null-terminated byte strings to compare s2 pointers to the null-terminated byte strings 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 NULL, r, s1, and s2.
