GETPAGESIZE(2)      Linux Programmer's Manual      GETPAGESIZE(2)

NAME
       getpagesize - get system page size

SYNOPSIS
       #include <unistd.h>

       size_t getpagesize(void);

DESCRIPTION
       Return  the  number  of bytes in a page.  This is the sys-
       tem's page size, which is not necessarily the same as  the
       hardware page size.

NOTES
       getpagesize  is  implemented  as a library function in DLL
       4.4.1.  Depending on what is defined when the  library  is
       compiled, this function returns EXEC_PAGESIZE (set to 4096
       in Linux 0.99.11), NBPG (set to 4096 in Linux 0.99.11), or
       NBPC   (not   defined   in  Linux  0.99.11  or  DLL  4.4.1
       libraries).

CONFORMING TO
       SVr4, 4.4BSD (this call first appeared in 4.2BSD).
