"GC" jargon "Jargon File (4.3.1, 29 Jun 2001)"
GC /G-C/ [from LISP terminology; `Garbage Collect'] 1. vt. To clean up
and throw away useless things. "I think I'll GC the top of my desk
today." When said of files, this is equivalent to GFR. 2. vt. To
recycle, reclaim, or put to another use. 3. n. An instantiation of the
garbage collector process.
`Garbage collection' is computer-science techspeak for a particular
class of strategies for dynamically but transparently reallocating
computer memory (i.e., without requiring explicit allocation and
deallocation by higher-level software). One such strategy involves
periodically scanning all the data in memory and determining what is no
longer accessible; useless data items are then discarded so that the
memory they occupy can be recycled and used for another purpose.
Implementations of the LISP language usually use garbage collection.
In jargon, the full phrase is sometimes heard but the abbrev GC is
more frequently used because it is shorter. Note that there is an
ambiguity in usage that has to be resolved by context: "I'm going to
garbage-collect my desk" usually means to clean out the drawers, but it
could also mean to throw away or recycle the desk itself.
"gc" foldoc "The Free On-line Dictionary of Computing (27 SEP 03)"
GC
1. garbage collection.
2. A storage allocator with garbage collection by
Hans-J. Boehm and Alan J. Demers. Gc is a plug-in replacement
for C's malloc. Since the collector does not require
pointers to be tagged, it does not attempt to ensure that
all inaccessible storage is reclaimed.
