how to claim array on shared memory

feetyouwell · 11-03-2004, 07:54 PM

supposed i have an array called abc[5], and i have created a shared memory with id as shmid
is this the correct way to put abc[5] onto shared memory?

abc = shmat(shmid, 0, 0)

thanks

I think that can be done by the following way.

if((shmid= shmget(SHMKEY,((sizeof(int))*5),IPC_CREAT0666))<0)
{
//error
}
if((arr=(int *)shmat(shmid,(char *)0,0))==(int *)-1)
{
// error
}

then u can use it as
a[i]=1;
