Hi,
In my program I hv two uuid_t type pointers.
I want to compare these two.
How can i do that?

eg code



int comuuid( uuid_t *uuid1 , uuid_t *uuid2 )

thanks a lot. I am new to C. it works now.

Hi, I tried to construct a simple program to generate an uuid.


#include <stdio.h>
#include <uuid/uuid.h>
int main()
{
get_uuid();
return 1;
}

sory its 127.0.1.1

I think this has no way to work out since my machine name (which I get by gethostname() method) is not in a DNS.
so I think it returns 127.0.0.1

any ideas about it?

Thanks.

now my programe is as follows.


char *hostname = malloc(MAXHOSTNAMELEN );
memset( hostname , 0 , MAXHOSTNAMELEN );

i tried with gethostname.
but it returns the hostname like "myLaptop".
I just need the ip like 192.168.10.10
my prev code was like as follows



memset( hostname , 0 , MAXHOSTNAMELEN );
...
