Chapter 6 Memory Manager Functions

AZNewPClr

DSNewPClr

syntax	UPtr		AZNewPClr(size);
	UPtr		DSNewPClr(size);
	XXNewPClr creates a new pointer to a nonrelocatable block of memory of the specified
	size and initializes the memory to zero.
	Parameter	Type	Description
	size	int32	Size, in bytes, of the pointer to create.
returns	A pointer to a block of size bytes filled with zeros. Returns NULL if the allocation
	could not be performed.

AZNewPtr

DSNewPtr

syntax		UPtr	AZNewPtr(size);
		UPtr	DSNewPtr(size);
	XXNewPtr creates a new pointer to a nonrelocatable block of memory of the specified
	size.
	Parameter	Type	Description
	size	int32	Size, in bytes, of the pointer to create.
returns		A pointer to a block of size bytes. Returns NULL if the allocation could not
		be performed.

Manipulating Properties of Handles

AZHLock

syntax

MgErr

AZHLock(h);

AZHLock locks the memory referenced by the application zone handle h so that the memory cannot move. This means the memory manager cannot move the block of memory to which the handle refers.

Do not lock handles more than necessary; it interferes with efficient memory management. Also, do not enlarge a locked handle.
