Kaim::SysAlloc Class Reference

#include <kernel.h>

Class Description

The SysAlloc class specifies an interface for allocating and freeing memory.

The BaseSystem maintains an instance of a class that implements the SysAlloc interface, which it makes available to all other Autodesk Navigation components. You can customize Autodesk Navigation memory management by writing your own implementation of the SysAlloc interface, and setting up the BaseSystem to use an instance of your custom class.

Examples:

Inherits Kaim::SysAllocBase.

Inherited by Kaim::MagicSysAlloc, and Kaim::SysAllocBase_SingletonSupport< SysAllocMalloc, SysAlloc >.

Member Function Documentation

void * Kaim::SysAlloc::Alloc ( UPInt  size, UPInt  align  )

pure virtual

Allocates a buffer of the specified size, with the specified alignment.

Parameters

size	The size of the requested buffer.
align	The alignment requested for the buffer.

Implemented in Kaim::SysAllocMalloc.

Examples:

void Kaim::SysAlloc::Free ( void *  ptr, UPInt  size, UPInt  align  )

pure virtual

Frees the specified memory buffer.

Parameters

ptr	The address of the buffer to be freed.
size	The size of the buffer to be freed.
align	The alignment of the buffer.

Implemented in Kaim::SysAllocMalloc.

Examples:

void * Kaim::SysAlloc::Realloc ( void *  oldPtr, UPInt  oldSize, UPInt  newSize, UPInt  align  )

pure virtual

Re-allocates a buffer to a new size.

Parameters

oldPtr	The current location of the buffer.
oldSize	The current size of the buffer.
newSize	The new desired size for the buffer.
align	The alignment requested for the new buffer.

Implemented in Kaim::SysAllocMalloc.
