GETPAGESIZE(3)

NAME
getpagesize - get system page size

LIBRARY
libc

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 underlying hardware page size.

p1003.1-2001 removed getpagesize. Portable applications should use ‘sysconf(_SC_PAGESIZE)’ instead.
