Function
Manipulates unique Object identifiers.
Syntax
#include <dx/dx.h>
int DXGetObjectTag(Object o)
Object DXSetObjectTag(Object o, int tag)
Functional Details
Every Object is assigned a unique nonzero integer tag when it is created. In addition, the executive sets the Object tag of Objects passed to and returned from modules by using DXSetObjectTag. This tag is used, for example, by the cache system to identify Objects. DXGetObjectTag returns the Object identifier tag for Object o. DXGetObjectTag can be used with the cache routines DXGetCacheEntry and DXSetCacheEntry to cache intermediate results between calls to a module.
| Note: | DXSetObjectTag is intended for use only by the executive and should not be used by module writers. |
Return Value
Returns the Object identifier or returns 0 and sets an error code.
