       getpagesize - Get the system page size

       #include <unistd.h>

       int getpagesize
	       void );

       Interfaces  documented on this reference page conform to industry stan‐
       dards as follows:

       getpagesize(): XSH4.2, XSH5.0

       The getpagesize() is marked as a LEGACY interface in the XSH specifica‐
       tion,  which recommends that portable applications use sysconf() rather
       than getpagesize().

       Refer to the standards(5) reference page	 for  more  information	 about
       industry standards and associated tags.

       The  getpagesize()  function returns the number of bytes in a page. You
       might need to include this value in  parameters	to  memory  management
       system calls.

       The  page  size	is an operating system page size and might differ from
       the underlying hardware page size.

       The getpagesize() function returns the number of bytes in a  page,  and
       is always successful.

       Functions:  brk(2),  getrlimit(2),  madvise(2),	mmap(2),  mprotect(2),
       msync(2), munmap(2)

       Routines: sysconf(3)
