NAME
       getpagesize -- get system page size

LIBRARY
       Standard	C Library (libc, -lc)

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	may not	be the same as the un-
       derlying	hardware page size.

       IEEE Std	1003.1-2001 ("POSIX.1")	removed	getpagesize.  Portable	appli-
       cations should use `sysconf(_SC_PAGESIZE)' instead.

HISTORY
       The getpagesize() function appeared in 4.2BSD.
