In computer science, Boehm-Demers-Weiser garbage collector, often simply known as Boehm GC, is a conservative garbage collector for C and C++, which is used by many projects that are implemented in C or C++, as well as by runtime environments for a number of other languages, including the Gnu Compiler for Java runtime environment, and the Mono implementation of the Microsoft .NET platform. It supports numerous operating systems, including many UNIX variants, Microsoft Windows, and Mac OS X, and provides a number of advanced features including incremental collection, parallel collection and a variety of finalizer semantics.

Example

The code piece below shows how one can use Boehm instead of traditional malloc and free in C [1]. malloc is a function for performing dynamic memory allocation in the C programming language. ...

 #include "gc.h" #include <assert.h> #include <stdio.h> int main() { int i; GC_INIT(); /* Optional on Linux/X86; see below. */ for (i = 0; i < 10000000; ++i) { int **p = (int **) GC_MALLOC(sizeof(int *)); int *q = (int *) GC_MALLOC_ATOMIC(sizeof(int)); assert(*p == 0); *p = (int *) GC_REALLOC(q, 2 * sizeof(int)); if (i % 100000 == 0) printf("Heap size = %dn", GC_get_heap_size()); } return 0; }
