Log:
Document what "msgsz" argument really denotes. [1]
Don't say that "msgsz" can be less than 0, it cannot
as it's unsigned (POSIX has the same bug).

msgsnd(3) page doesn't make it clear whether the 'msgsz' argument refers to the length of the entire *msgp structure (mtype + mtext) or just to the length of the data in mtext. Fix: The Linux manpage is clearer: it says The mtext field is an array (or other structure) whose size is speci- fied by msgsz, a non-negative integer value. Messages of zero length (i.e., no mtext field) are permitted. But perhaps a simple fix for us is: mtype is an integer greater than 0 that can be used for selecting mes- sages (see msgrcv(3)); mtext is an array of msgsz bytes, which may be between 0 and the system limit (MSGMAX). How-To-Repeat: man 3 msgsnd
