GETPAGESIZE(3) 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 underly- ing hardware page size. IEEE Std 1003.1-2001 ("POSIX.1") removed getpagesize. Portable applica- tions should use `sysconf(_SC_PAGESIZE)' instead. SEE ALSO pagesize(1), sbrk(2), getpagesizes(3), sysconf(3) HISTORY The getpagesize() function appeared in 4.2BSD. FreeBSD 15.1 October 17, 2022 GETPAGESIZE(3)
