NAME
       getpagesize - get system page size

SYNOPSIS
       #include <unistd.h>

       int getpagesize(void);

DESCRIPTION
       The  getpagesize() function 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 need not be  the	 same  as  the
       underlying hardware page size.

       The  getpagesize() function is equivalent to sysconf(_SC_PAGE_SIZE) and
       sysconf(_SC_PAGESIZE). See sysconf(3C).

RETURN VALUES
       The getpagesize() function returns the current page size.

ERRORS
       No errors are defined.

USAGE
       The value returned by getpagesize() need not be the minimum value  that
       malloc(3C)  can allocate.  Moreover, the application cannot assume that
       an object of this size can be allocated with malloc().
