函数名: strncmpi
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 strncmpi(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 = strcmpi(buf2, buf1); if (ptr > 0)
printf("buffer 2 is greater than buffer 1
"); if (ptr < 0)
printf("buffer 2 is less than buffer 1
"); if (ptr == 0)
printf("buffer 2 equals buffer 1
"); return 0;
}
