将C ++回调函数导入delphi

Question

这是此函数的C ++标头。我已经导入了一切，除了那个calllback我不知道怎么做。

struct abs_operation;

typedef struct abs_operation ABS_OPERATION;  /* forward declaration */

typedef void (BSAPI  *ABS_CALLBACK) ( const ABS_OPERATION*, ABS_DWORD, void*);

struct abs_operation {
        ABS_CALLBACK Callback;  ///< Pointer to application-defined function, implementing operation callback.
} ;

Answer 1

根据您之前问题的知识，我想是这样的：

type
  PABSOperation = ^TABSOperation;
  TABSCallback = procedure(const Operation: PABSOperation;
     Flags: DWORD; Ptr: Pointer); stdcall;
  TABSOperation = record
     Callback: TABSCallback;
  end;
