Compares, with case insensitivity, a specified number of characters in one string to another string.
#include <string.h> int Lstrnicmp ( const char *s1, const char *s2, size_t len);
(IN) Points to a string to compare.
(IN) Points to a 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 Lstrnicmp function is a double-byte character interface. It compares, with case insensitivity, the string pointed to by s1 to the string pointed to by s2, for at most len characters.
