getpagesize(3)          (BSD Compatibility Package)          getpagesize(3)

NAME
     getpagesize - get system page size

SYNOPSIS
     /usr/ucb/cc [flag ...] file ... -lucb

     #include <unistd.h>

     int getpagesize(void);

DESCRIPTION
     getpagesize returns the number of bytes in a page. Page granularity is
     the granularity of many of the memory management calls.

     The getpagesize() function is equivalent to sysconf(SCPAGESIZE) and
     sysconf(SCPAGESIZE).

     The page size is a system page size and need not be the same as the
     underlying hardware page size.

     msync(3C), sysconf(3C), unistd(4).
