E2141 Declaration syntax error

[setdefault]

.h中定义：
typedef struct _st_CylindricalCoordinate{
float z,
r,
angle;
}st_CylindricalCoordinate;
class TSAR{
st_CylindricalCoordinate FindPoint(
st_CylindricalCoordinate *StartPoint,
float Step,
enum_ShiftDirection ShiftDirection
);

};

.cpp中

st_CylindricalCoordinate TSAR::FindPoint( //本行TSAR处出错
st_CylindricalCoordinate *StartPoint,
float Step,
enum_ShiftDirection ShiftDirection
)
{
...
}

为什么会？谁能帮办我？
我把返回值改成bool类型就没有错误

偶不会出错~~~~~~~~~~郁闷

是啊，3996906(以后再说)，我也做了相同的事，结果一样。
我原来是返回bool类型，今天改成这样的结构就出现这个问题。确实不知怎么办？郁闷
建议一下那儿可能会导致这样的错误？

找到原因了。3996906(以后再说)，是我描述有误，我把typedef struct _st_CylindricalCoordinate{
float z,
r,
angle;
}st_CylindricalCoordinate；定义在类内部了。
在实现的时候这样写就行：
TSAR::st_CylindricalCoordinate TSAR::FindPoint(....)
{
....
}
