The
.I advice
values listed below
allow an application to tell the kernel how it expects to use
some mapped or shared memory areas, so that the kernel can choose
appropriate read-ahead and caching techniques.
These
.I advice
values do not influence the semantics of the application
(except in the case of
-.BR MADV_DONTNEED ),
+.BR MADV_DONTNEED
+and
+.BR MADV_WIPEONFORK ),
but may influence its performance.
All of the
.I advice
values listed here have analogs in the POSIX-specified
.BR posix_madvise (3)
function, and the values have the same meanings, with the exception of
.BR MADV_DONTNEED .

The advice is indicated in the
