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  system'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).
