Applied, thanks.
fdisk.c: In function ‘get_random_id’:
fdisk.c:160: warning: implicit declaration of function ‘time’
fdisk.c: In function ‘create_doslabel’:
fdisk.c:803: warning: unused variable ‘i’
fixed ;-)
BTW, I've read libparted code and there is:
static inline uint32_t generate_random_id()
{
struct timeval tv;
int rc;
rc = gettimeofday(&tv, NULL);
if (rc == -1)
return 0;
return (uint32_t)(tv.tv_usec & 0xFFFFFFFFUL);
}
