SYNOPSIS

       #include <unistd.h>

       size_t getpagesize(void);


DESCRIPTION

       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).
