@deftypefn Supplemental int getpagesize (void)
|
|
|
|
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.
