DESCRIPTION    [Toc]    [Back]

     This   interface   is   obsoleted   by   sysconf(3).     Use
sysconf(_SC_PAGESIZE).

     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 underlying
 hardware page size.
