驱动调动出错 [复制链接]

现在我遇到的问题是:
.h 文件
#ifndef LIBPTIHDLC_H
#define LIBPTIHDLC_H

#ifdef __cplusplus

extern "C"
{

#endif //__cplusphus


int PtiHdlcOpen(const int ctrl, const int link, const int baud);

#ifdef __cplusplus
}

#endif //__cplusplus

#endif //LIBPTIHDLC_H

我已经声明为extern"C" 为什么在函数实现里面,它不调用MPSopen(&oreq)而调用MPSopen(); 我用MPSopen(&oreq)提示参数太多,后者就没事    问题关键用红色标记了 谢谢了
