is getaddrinfo memory leak?

hi all:
my program use getaddrinfo £¬but when i use valgrind check memory
leak it show getaddrinfo memory leak
code:
int checkAddrType(const char *addr,const char *hostip)
{
struct sockaddr_in ad,*adp;
struct addrinfo hints,*result;
char buf[100];

if(inet_pton(PF_INET,addr,&ad.sin_addr)<=0)
{
memset(&hints,0,sizeof(hints));
hints.ai_family=PF_UNSPEC;
hints.ai_socktype=SOCK_STREAM;
if(getaddrinfo(addr,"www",&hints,&result)!=0)
{
return -1;
}

adp=(struct sockaddr_in *)result->ai_addr;
inet_ntop(PF_INET,&adp->sin_addr,buf,100);
freeaddrinfo(result);
if(compIp(buf,hostip)==0)
return 2;
return 3;

}

if(compIp(addr,hostip)==0)
return 1;

return 0;
}
test code:

#include <addressinfo.h>

int main(int argc,char **argv)
{

int i;

for(i=0;i<1000;i++)
{
checkAddrType("www.zju.edu.cn","10.10.8.22");
}

return 0;
}
