函数名: strnicmp

功 能: 将一个串中的一部分与另一个串比较, 不管大小写

用 法: int strnicmp(char *str1, char *str2, unsigned maxlen);

程序例:

#include <string.h>

#include <stdio.h>

int main(void)

{

char *buf1 = "BBB", *buf2 = "bbb";

int ptr;

ptr = strnicmp(buf2, buf1);

if (ptr > 0)

printf("buffer 2 is greater than buffer 1\");

else if (ptr < 0)

printf("buffer 2 is less than buffer 1\");

else

printf("buffer 2 equals buffer 1\");

return 0;

}
