mqueue.h(3HEAD) Headers mqueue.h(3HEAD)NAME
mqueue.h, mqueue - message queues
SYNOPSIS
#include <mqueue.h>
DESCRIPTION
The <mqueue.h> header defines the mqd_t type, which is used for message queue descriptors. This will not be an array type. A message
queue descriptor may be implemented using a file descriptor, in which case applications can open up to at least OPEN_MAX file and message
queues.
The <mqueue.h> header defines the sigevent structure (as described in <signal.h>, see signal.h(3HEAD)) and the mq_attr structure, which is
used in getting and setting the attributes of a message queue. Attributes are initially set when the message queue is created. A mq_attr
structure has the following members:
long mq_flags message queue flags
long mq_maxmsg maximum number of messages
long mq_msgsize maximum message size
long mq_curmsgs number of messages currently queued
Inclusion of the <mqueue.h> header may make visible symbols defined in the headers <fcntl.h>, <signal.h>, <sys/types.h>, and <time.h>.

Folks,
Does anyone know the magic to balancing out the:
DFLT_MSGMAX and the DFLT_MSGSIZEMAX values?
Is there some magical formula... We have a home grown program that
is choking we think because of these values (the 10 and the 8192 defaults)
Thanks,
