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 underlying hardware page size.

The `getpagesize`() function call appeared in 4.1cBSD.
