the following:
"The queue capacity is defined by the msg_bytes field in
the associated data structure for the message queue."
If I'm not wrong, the exact name of that field in the
msqid_ds structure is msg_qbytes. The same thing appears
also on the online [POSIX] manual pages, I checked it
already.
I provided a detailed confirmation with quotes from the
Linux kernel sources:

This patch (requested by Mihail) makes the correction and
removes unnecessary implementation details.
