	AIX development is not needed to answer this question.  One query
the total physical memory in the system through the _system_configuration
implicitly exported symbol which returns the number of bytes of physical
memory as a long long int:


#include <stdio.h>
#include <sys/systemcfg.h>

int main(void)
{
  printf ("total=%lld Mb\n",
          _system_configuration.physmem / (1024 * 1024));
  
  return 0;
}

	Available memory requires querying the VMM system which is
privileged.
