Compares a specified number of characters between two strings.
#include <string.h>
int Lstrncmp (
const char *s1,
const char *s2,
size_t n);
(IN) Points to the string to compare.
(IN) Points to the string to compare.
(IN) Specifies the number of characters to compare.
Returns 0 if the two strings match. Otherwise, returns an integer less than or greater than 0, depending on whether s1 is lexicographically less than or greater than s2.
The Lstrncmp function is a double-byte character interface. It compares not more than n characters from the string pointed to by s1 to the string pointed to by s2. Characters that follow a NULL character are not compared.
