    typedef struct mmemory {
        int* cells;
        int* current_cell;
        int cells_number;
    } memory;

    void memory_init(memory* mymemory,int size);
    void step_left(memory* mymemory,int steps);

    void print_cell(memory* mymemory);
    void get_char(memory* mymemory);


#ifdef  __cplusplus
}
#endif

#endif  /* MEMORY_H */

而这个实现文件(memory.c)

#include <stdlib.h>
#include "memory.h"

void
memory_init (memory* mymemory,int size)
{
    mymemory->cells = (int*) malloc (sizeof (int) * size);
    mymemory->cells_number = size;
    mymemory->current_cell = (int*) ((mymemory->cells_number / 2) * sizeof (int));
}
... //other function definitions follow

当我尝试编译memory.c时,每个函数定义都会出现此错误

src/memory.c:5: error: expected ‘)’ before ‘*’ token

其中第5行是memory_init()的函数定义

有人可以告诉我为什么我收到此错误？
