main()

{

int shmid,i,len;

char *pa,a[1000];

shmid=shmget((key_t)1300,1024,0600|IPC_CREAT);

if(shmid==-1)

{printf("shmget failed");

return;

}

pa=(char*)shmat(shmid,0,0);

if(pa==(void *)-1)

{

printf("shmat failed");

return;

}

len=strlen(pa);

printf("\nThe length of the text is : %d\n",len);

}

OUTPUT:

[user @localhost ~]$ cc lenshm.c
