# Memory Abstraction

All dynamic memory allocations in Export modules are abstracted through a C interface. This memory allocation interface is defined in the `KVMemoryStream` structure in `kvtypes.h`. See KVMemoryStream. You can override all memory allocations by providing a C structure that contains pointers to functions identical in nature to their standard ANSI C counterpart.

The callback sample program demonstrates Export memory management features.
