How are you marking the length of a message with writing to the pipe? Are you writing the length first, then the bytes, and when it comes to reading you read the length first, then that exact number of bytes?
NO.....currently I am not considering length........because first I am testing for fixed size string.........
how should I make my child not to interfear with parents data.........
because I will not terminate my child then the code.......after read and write operation is executed twice once by parent and one by child.......
how should i use my child process......???? so that it also continously read data from message queue and write to pipe....

msg_get_queue
MSG_GET_QUEUE(3) 1 MSG_GET_QUEUE(3)
msg_get_queue - Create or attach to a message queue
SYNOPSIS
resource msg_get_queue (int $key, [int $perms = 0666])
DESCRIPTION
msg_get_queue(3) returns an id that can be used to access the System V message queue with the given $key. The first call creates the mes-
sage queue with the optional $perms. A second call to msg_get_queue(3) for the same $key will return a different message queue identifier,
but both identifiers access the same underlying message queue.
PARAMETERS
o $key
- Message queue numeric ID
o $perms
- Queue permissions. Default to 0666. If the message queue already exists, the $perms will be ignored.
RETURN VALUES
Returns a resource handle that can be used to access the System V message queue.
SEE ALSO
msg_remove_queue(3), msg_receive(3), msg_send(3), msg_stat_queue(3), msg_set_queue(3).
