param.h

Purpose

     Describes system parameters.

Synopsis

     #include <sys/param.h>

Description

     Parameters  vary among  systems using  the AIX  operating
     system.   For the  RT PC,  these parameters  are in  this
     file.  The most significant parameters are:

     BSIZE Indicates  the kernel  buffer  size.  RT  PC has  a
           buffer  size of  2048 bytes.   This determines  the
           size of block clusters on a file system.  Since the
           size  of a  block  is  512 bytes,  a  cluster is  4
           blocks.

     NOFILE  Indicates  the  maximum  open  file  allowed  per
           process.  This value is 200.

     NCARGS  Indicates  the   maximum  number  of  characters,
           including terminating NULs that may be passed using
           the exec system call.
