GETPAGESIZE(3) FreeBSD 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
underlying hardware page size.
IEEE Std 1003.1-2001 ("POSIX.1") removed getpagesize. Portable
applications should use `sysconf(_SC_PAGESIZE)' instead.
SEE ALSO
