NAME

6       getpagesize - get system page size
7

SYNOPSIS

9       #include <unistd.h>
10
11       int getpagesize(void);
12
13

DESCRIPTION

15       The  getpagesize() function returns the number of bytes in a page. Page
16       granularity is the granularity of many of the memory management calls.
17
18
19       The page size is a system page size and need not be  the  same  as  the
20       underlying hardware page size.
21
22
23       The  getpagesize() function is equivalent to sysconf(_SC_PAGE_SIZE) and
24       sysconf(_SC_PAGESIZE). See sysconf(3C).
25

RETURN VALUES

27       The getpagesize() function returns the current page size.
28

ERRORS

30       No errors are defined.
31

USAGE

33       The value returned by getpagesize() need not be the minimum value  that
34       malloc(3C)  can allocate.  Moreover, the application cannot assume that
35       an object of this size can be allocated with malloc().
