run-time settting of PIPE_BUF

[zdenko tomasic]

Does anybody know how to change the pipe buffer PIPE_BUF? I suspect
that it has a value of 512 bytes (POSIX conformance?), but according
to /usr/include/sys/limits.h, it can be increased to 32KB at
run-time. I was not able to find out from info how to achieve that.
Default pipe behavior in AIX is rather inefficient with too many
context switches.

Thanks for your attention.
