#!N #!N #!N #!N On platforms without per-processor local memory (such 
as all currently supported workstations),  #!F-adobe-times-bold-r-normal--18*   DXAllocateLocal #!EF is identical to 
 #!F-adobe-times-bold-r-normal--18*   DXAllocate #!EF . #!N #!N Although local is usually faster 
than global access, local memory should be used only for Objects 
within a task or for parts of a module not in 
a task Group: Objects in local memory cannot be shared between 
processors. Objects that are the output of a module must be 
in global memory. Note: Memory allocated by any routine listed here 
should be freed (with DXFree) when it is no longer needed. 
#!N #!N Return Value Returns a pointer to the allocated memory 
or returns  #!F-adobe-times-bold-r-normal--18*   NULL #!EF and sets an error code. #!N
