aggregate_de.h

Blood 2全套源码

// This header file defines the base aggregate structure.  Every
// aggregate must have a link to its next one and a pointer
// to certain functions that an aggregate must supply.
// When implementing an aggregate, you MUST derive from this!
// (In C, just put it as the first member in your structure..)
