nsMemory

Summary

The nsMemory class provides static helper routines to manage memory. These routines allow easy access to XPCOM's global nsIMemory implementation without having to go through the service manager to get it.

#include "nsMemory.h"

class nsMemory { ... };

Methods

Alloc
The Alloc function allocates a block of memory of a particular size.
Realloc
The Realloc function reallocates a block of memory to a new size.
Free
The Free function frees a block of memory that was allocated by XPCOM's memory manager.
HeapMinimize
The HeapMinimize function attempts to shrink the size of the heap.
Clone
The Clone function creates a copy of an existing memory block up to the size specified.
GetGlobalMemoryService
The GetGlobalMemoryService function returns a reference to XPCOM's global nsIMemory object.

Remarks

To use the methods in this class, you must link your component or application against the XPCOM glue library.

The static methods defined on this class are not frozen. However, if you use these functions in your XPCOM component, and if you link to the XPCOM glue library, then your component will only have a runtime dependency on the frozen XPCOM API.
