Detailed Description

This information is stored in memory allocated by the <Memory_Pool>.

This class defines the "old" control block class for use in ACE_Malloc_T. This control block implementation is considerable more efficient than the "position independent" one below (ACE_PI_Control_Block) but if you are going to use it to construct a ACE_Malloc_T and access the memory from several different processes, you must "map" the underlying memory pool to the same address.
