Struct std.experimental.allocator.mallocator.Mallocator

The C heap allocator.

struct Mallocator ;

Fields

NameTypeDescription
instance shared(Mallocator)Returns the global instance of this allocator type. The C heap allocator is thread-safe, therefore all of its methods and it itself are shared.

Methods

NameDescription
allocate (bytes) Standard allocator methods per the semantics defined above. The deallocate and reallocate methods are @system because they may move memory around, leaving dangling pointers in user code. Somewhat paradoxically, malloc is @safe but that's only useful to safe programs that can afford to leak memory allocated.
deallocate (b) Standard allocator methods per the semantics defined above. The deallocate and reallocate methods are @system because they may move memory around, leaving dangling pointers in user code. Somewhat paradoxically, malloc is @safe but that's only useful to safe programs that can afford to leak memory allocated.
reallocate (b, s) Standard allocator methods per the semantics defined above. The deallocate and reallocate methods are @system because they may move memory around, leaving dangling pointers in user code. Somewhat paradoxically, malloc is @safe but that's only useful to safe programs that can afford to leak memory allocated.

Example

auto buffer = Mallocator.instance.allocate(1024 * 1024 * 4);
scope(exit) Mallocator.instance.deallocate(buffer);
