DESCRIPTION
\nThe\u00a0 msgsnd()\u00a0 and\u00a0 msgrcv() system calls are used, respectively, to send messages to, and receive messages from, a message queue.\u00a0 The calling process must have write permission on the
\nmessage queue in order to send a message, and read permission to receive a message.<\/p>\n

The msgp argument is a pointer to caller-defined structure of the following general form:<\/p>\n

struct msgbuf {
\nlong mtype;\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 \/* message type, must be > 0 *\/
\nchar mtext[1];\u00a0\u00a0\u00a0 \/* message data *\/
\n};<\/p>\n

The mtext field is an array (or other structure) whose size is specified by msgsz, a nonnegative integer value.\u00a0 Messages of zero length (i.e., no mtext field) are permitted.\u00a0 The mtype
\nfield must have a strictly positive integer value.\u00a0 This value can be used by the receiving process for message selection (see the description of msgrcv() below).<\/p>\n
