GETPAGESIZE(3)		     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
     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 underly-
     ing hardware page size.

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

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

HISTORY
     The getpagesize() function appeared in 4.2BSD.

FreeBSD ports 15.1		October 17, 2022		  GETPAGESIZE(3)
