Q3HandleStorage_New

You can use the Q3HandleStorage_New function to create a new handle storage object.

TQ3StorageObject Q3HandleStorage_New (
Handle handle, 
unsigned long validSize);

handle

A handle to a buffer in memory, or NULL.

validSize

The size, in bytes, of the specified buffer.

DESCRIPTION

The Q3HandleStorage_New function returns, as its function result, a new handle storage object associated with the buffer specified by the handle and validSize parameters. Your application must not access that buffer until the associated storage object is closed or disposed of. If Q3HandleStorage_New cannot create a new storage object, it returns the value NULL. If you pass the value NULL in the handle parameter, QuickDraw 3D allocates a buffer of the specified size and later disposes of that buffer when the associated storage object is closed or disposed of.
