memicmp
原型:extern int memicmp(void *buf1, void *buf2, unsigned int count);
用法:#include <string.h>
功能:比较内存区域buf1和buf2的前count个字节但不区分字母的大小写。
说明:memicmp同memcmp的唯一区别是memicmp不区分大小写字母。
当buf1<buf2时,返回值<0
当buf1=buf2时,返回值=0
当buf1>buf2时,返回值>0
举例:
// memicmp.c
#include <syslib.h>
#include <string.h>
main()
{
char *s1="Hello, Programmers!";
char *s2="Hello, programmers!";
int r;
clrscr();
r=memicmp(s1,s2,strlen(s1));
if(!r)
printf("s1 and s2 are identical");
else
if(r<0)
printf("s1 less than s2");
else
printf("s1 greater than s2");
getchar();
return 0;
}
