Memory operations are common for whole CDS library. Because it must work together with SER's memory management and must work without it too, there are wrapper macros for memory allocation/deallocation. These macros were functions and it may change in the future, but macros are probably better - they allow better debuging than functions. There are defined another macros (see , ), which point and will point to allocation/deallocation functions, thus they may be used as function pointers. It is possible to redefine these macros/functions to help with memory debugging or for monitoring purposes or so.
