-/* Emulation of getpagesize() for systems that need it. */

-NAME
-
- getpagesize -- return the number of bytes in page of memory
-
-SYNOPSIS
-
- int getpagesize (void)
-
-DESCRIPTION
-
- Returns the number of bytes in a page of memory. This is the
- granularity of many of the system memory management routines.
- No guarantee is made as to whether or not it is the same as the
- basic memory management hardware page size.
-
-BUGS
-
- Is intended as a reasonable replacement for systems where this
- is not provided as a system call. The value of 4096 may or may
- not be correct for the systems where it is returned as the default
- value.
