Dynamically load and bind libraries for which GObjectIntrospection data is available. This article assumes you're familiar with C and C++. The access of automatic variables is a very fast assisted by hardware, so there is no loss of efficiency there. Unfortunately, these benefits have not If the programmer uses our library for allocating memory dynamically, we will make sure (conservatively) that the allocated memory is automatically freed (i.e.) garbage is collected when it is no longer referenced. Perhaps this was a decent reaction to the memory management of C, but as a whole, in general purpose languages, garbage collection is more of a detriment than a benefit. These are not garbage collected - you need to explicitly free every pointer that you allocated. Garbage collection deals with the automatic management of dynamic memory. There is no actual allocation or deallocation going on: the space in the automatic memory (AKA "on the stack") is allocated by some compile-time bookkeeping around the stack pointer. Nevertheless, all of the commonly used JVMs have garbage collectors, and most garbage collectors use similar algorithms to manage their memory and perform collection operations. Automatic memory management enables increased The main problem for most dynamic memory allocation algorithms is to avoid fragmentation (see below), while keeping both allocation and deallocation efficient. An alternate approach to memory management that is now commonly utilized, especially by most modern object-oriented languages, is automatic management by a program called a garbage collector.

Garbage Collection Part 2: Automatic Memory Management in the Microsoft . Methods, constructors Garbage collector integration with GObject reference counts for automatic memory management. Nor does it specify how a garbage collector should work. Garbage Collection: Automatic Memory Management in the Microsoft .NET Framework. Software professionals estimate that the programming effort required to manually perform dynamic memory management is approximately 40% of the total cost of developing a large software system. Furthermore, the simplified model requires hiding the true nature of memory making it more difficult to implement certain inter-process and concurrent programming algorithms. A half way to garbage collection is to use private heaps, that is, you first allocate a big chunk of memory and manage it in a Heap class (whenever you need new memory to be allocated, a request is being made to the Heap class). Dynamic memory allocation (Java-style) is done with malloc / calloc / realloc in C.
