|
|
|
|
|
The Boehm-Demers-Weiser conservative garbage collector can be used as a
|
|
|
|
|
garbage collecting replacement for C malloc or C++ new. It allows you
|
|
|
|
|
to allocate memory basically as you normally would, without explicitly
|
|
|
|
|
deallocating memory that is no longer useful. The collector
|
|
|
|
|
automatically recycles memory when it determines that it can no longer
|
|
|
|
|
be otherwise accessed.
|
|
|
|
|
|
|
|
|
|
The collector is also used by a number of programming language
|
|
|
|
|
implementations that either use C as intermediate code, want to
|
|
|
|
|
facilitate easier interoperation with C libraries, or just prefer the
|
|
|
|
|
simple collector interface.
|
|
|
|
|
|
|
|
|
|
Alternatively, the garbage collector may be used as a leak detector for
|
|
|
|
|
C or C++ programs, though that is not its primary goal.
