NAME
     getpagesize - get system page size

SYNOPSIS
     #include <unistd.h>

     int getpagesize (void);

DESCRIPTION
     Getpagesize returns the number of bytes in a page.	 Page granularity is
     the granularity of many of the memory management calls.

     The page size is a system page size and may not be the same as the
     underlying hardware page size.

     In systems with multiple page sizes, the base page size is returned. The
     base page size is the smallest page size used by a system.
