        Hi, managers,

I would like to know, if it is possible to increase receive/send
buffer size for an AF_UNIX socket:

        setsockopt works fine but the limit is :

                2048 bytes on DU 3.2c.
                4080 bytes (strange isn'it) on DU 4.0B

Quite small for an interprocess communication chanel!

If a process doesn't empty the receiving buffer as fast as it's filled up we
get very quickly an ENOBUFFS errno message on the sendto (oups !! error
referenced in the write (2) manual page, thanks to the sendto manual page!).


Thank you, and I'll summarize...
