HeapAllocFlags indicate how the block should be allocated and initialized. They are not stored and can not be retrieved. Only some of the flags can be passed with MemReAlloc() ; these are noted below. The following flags are available:

HAF_ZERO_INIT

The memory manager should initialize the block to null bytes. This flag may be passed to MemReAlloc() to cause new memory to be zero-initialized.

HAF_LOCK

The memory manager should lock the block after allocating it. To get the block's address, call MemDeref() . This flag may be passed to MemReAlloc() .

HAF_NO_ERR

The memory manager should not return errors. If it cannot allocate block, GEOS will tell the user that there is no memory available and crash. Use of this flag is strongly discouraged. This flag may be passed to MemReAlloc() .

HAF_UI

If both HAF_OBJECT_RESOURCE and HAF_UI are set, this block will be run by the application's UI thread.

HAF_READ_ONLY

The block's data will not be modified. Useful for the debugger.

HAF_OBJECT_RESOURCE

This block will be an object block.

HAF_CODE

This block contains executable code.

HAF_CONFORMING

If the block contains code, the code may be run by a less privileged entity. If the block contains data, the data may be accessed or altered by a less privileged entity.
