NAME

getpagesize — get system page size

SYNOPSIS

#include <unistd.h>

int
getpagesize(void);

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 underlying hardware page size.

The getpagesize() function call appeared in 4.2BSD.
