From The Free On-line Dictionary of Computing (19 Sep 2003) [foldoc]:
fence
1. A sequence of one or more distinguished (out-of-band)
characters (or other data items), used to delimit a piece of
data intended to be treated as a unit (the computer-science
literature calls this a "sentinel"). The NUL (ASCII 0000000)
character that terminates strings in C is a fence. Hex FF
is also (though slightly less frequently) used this way. See
zigamorph.
2. An extra data value inserted in an array or other data
structure in order to allow some normal test on the array's
contents also to function as a termination test. For example,
a highly optimised routine for finding a value in an array
might artificially place a copy of the value to be searched
for after the last slot of the array, thus allowing the main
search loop to search for the value without having to check at
each pass whether the end of the array had been reached.
3. [among users of optimising compilers] Any technique,
usually exploiting knowledge about the compiler, that blocks
certain optimisations. Used when explicit mechanisms are not
available or are overkill. Typically a hack: "I call a dummy
procedure there to force a flush of the optimiser's
register-colouring info" can be expressed by the shorter
"That's a fence procedure".
