+.SH NAME
+sys/msg.h
+\(em XSI message queue structures
+.SH SYNOPSIS
+.LP
+.nf
+#include <sys/msg.h>
+.fi
+.SH DESCRIPTION
+The
+.IR <sys/msg.h> 
+header shall define the following data types through
+.BR typedef :
+.IP "\fBmsgqnum_t\fP" 14
+Used for the number of messages in the message queue.
+.IP "\fBmsglen_t\fP" 14
+Used for the number of bytes allowed in a message queue.
+.P
+These types shall be unsigned integer types that are able to store
+values at least as large as a type
+.BR "unsigned short" .
+.P
+The
+.IR <sys/msg.h> 
+header shall define the following symbolic constant as a message
+operation flag:
+.IP MSG_NOERROR 14
+No error if big message.
+.P
+The
+.IR <sys/msg.h> 
+header shall define the
+.BR msqid_ds
+structure, which shall include the following members:
+.sp
+.RS 4

+msgqnum_t       msg_qnum   \fRNumber of messages currently on queue.\fR
+msglen_t        msg_qbytes \fRMaximum number of bytes allowed on queue.\fR

+The
+.IR <sys/msg.h> 
+header shall define the
+.BR pid_t ,
+.BR size_t ,
+.BR ssize_t ,
+and
+.BR time_t
+types as described in
+.IR <sys/types.h> .
+.P
+The following shall be declared as functions and may also be defined
+as macros. Function prototypes shall be provided.
