GETPAGESIZE(3)            OpenBSD Programmer's Manual           GETPAGESIZE(3)

NAME
     getpagesize - get system page size



SYNOPSIS
     #include <unistd.h>

     int
     getpagesize(void);

DESCRIPTION
     This interface is obsoleted by sysconf(3).  Use sysconf(_SC_PAGESIZE).

     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 under-
     lying hardware page size.

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

     The getpagesize() function call appeared in 4.2BSD.
