GETPAGESIZE(3)		 BSD Library Functions Manual		GETPAGESIZE(3)

NAME
     getpagesize — get system page size

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <unistd.h>

     int
     getpagesize(void);

DESCRIPTION
     This interface is obsoleted by sysconf(3).

     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 under‐
     lying hardware page size.

SEE ALSO
     pagesize(1), sbrk(2), sysconf(3)

HISTORY
     The getpagesize function call appeared in 4.2BSD.
