In this release, instead of using “new” to allocate heap memory in xAF interface classes, pointers to memory allocator and de-allocator methods are now passed in during initialization:<\/p>\n
typedef void* (*memAlloc)(unsigned int, unsigned int);
\ntypedef void (*memDeAlloc)(void*);<\/p>\n
This was done for the following classes\/structs:<\/p>\n
Master Control:<\/span><\/p>\n When calling xAFInitMasterControl, the application now needs to pass in an allocator pointer, alloc.\u00a0<\/em><\/p>\n enum xAF_Error xAFInitMasterControl(xAFSMasterControl* p_masterControl, unsigned int* ControlConfig, unsigned int maxPins, unsigned int maxXafInstance, memAlloc alloc<\/em><\/strong><\/span>);<\/p>\n memAlloc is simply a pointer to a memory allocation method defined by the application:<\/p>\n Similarly, for deallocation, a de-allocation memory pointer needs to also be passed in:<\/p>\n void xAFDeallocMasterControl(xAFSMasterControl* p_masterControlstruct, memDeAlloc deAlloc<\/em><\/strong>);<\/p>\n Chunk Parser:<\/span><\/p>\n ChunkParser is the base class that multiple parsing classes inherit from including DSFDParser and DeviceParser. When initializing it, the application has to pass both allocator and de-allocator pointers:<\/p>\n xAF_Error init(IOBase* theInterface, char(&identifierString)[4], memAlloc allocator, memDeAlloc deAllocator<\/em><\/strong>);<\/p>\n Initialization Message Parser:<\/span><\/p>\n This class is responsible for saving the xTP signal flow data into flash\/persistent memory on an amplifier. Accordingly, a memory allocator needs to be passed into the method that allows the parser to access the flash memory:<\/p>\n typedef FlashInterface* (*openMemoryStorage_t)(memAlloc alloc<\/em><\/strong>, flashfileType type, unsigned int coreID, unsigned int instanceID, IOBase::AccessMode mode);<\/p>\n The allocator and deallocators also need to be passed into the method to
