有点难度……一个infosec_api.h文件，一个与之相关的certinfo.lib文件。目标：写一个组件要在能在ASP中创建，并且能调用infosec_api.h中定义的各个函数……

在BCB中应该具体怎样声明？？
infosec_api.h 源文件如下：
#ifndef _INFOSEC_API_
#define _INFOSEC_API_


#ifdef WIN32
#ifndef DLLENTRY
#define DLLENTRY __declspec(dllimport)
#endif
#else
#define DLLENTRY
#endif

#ifdef __cplusplus
extern "C" {
#endif

/*

DLLENTRY int sign(char *src,int srcLen,char *privateKey,

/*
