NAME
     msg.h, msg - message queue structures

SYNOPSIS
     #include 


DESCRIPTION
     The  header  defines  the  following  data  types
     through typedef:

     msgqnum_t    used for the number of messages in the  message
                  queue


     msglen_t     used for the number of  bytes  allowed  in  the
                  message queue



     These types are unsigned integer  types  that  are  able  to
     store values at least as large as a type unsigned short.


     The  header defines the following constant  as  a
     message operation flag:

     MSG_NOERROR    no error if big message



     The msqid_ds structure contains the following members:

       struct ipc_perm    msg_perm      Operation permission structure.
       msgqnum_t          msg_qnum      Number of messages currently on
                                        queue.
       msglen_t           msg_qbytes    Maximum number of bytes allowed
                                        on queue.
       pid_t              msg_lspid     Process ID of last msgsnd(2).
       pid_t              msg_lrpid     Process ID of last msgrcv(2).
       time_t             msg_stime     Time of last msgsnd().
       time_t             msg_rtime     Time of last msgrcv().
       time_t             msg_ctime     Time of last change.



     The pid_t, time_t, key_t,  size_t,  and  ssize_t  types  are
     defined as described in . See types(3HEAD).
