Following is an request I am posting for a friend that doesn't have net
access. Please respond to the voice phone number given at the end of the
article.

I am wondering if anyone has source to help me with a problem I have
encountered in a project I am working on. I am using
System V (Venix) and need more messages outstanding in the
message queues than apparently the system will alow.
According to what I decypher from mtune, I can only have
40 messages outstanding systemwide. But the biggest limitation
is the 128K limitation due to the way message queues are
implemented.
Essentially, my requirements are as follows:
Message length max = 512 (may get by with 256 bytes)
40 queues
Max # of outstanding messages = 500
Different queues may have different max message lengths.
The messages need to be accessed randomly. (Not FIFO)
What I am hoping for is that someone has developed the code
implementing message queues in shared memory.
I can be reached at (daytime, voice)
