自定义函数调用时提示参数错误！～
语法错误，求教

The extern function declaration is used to declare functions that are not part of TSL, but reside in external C libraries.

For more information on using C functions stored in external dlls, refer to your User's Guide.

int(); 对参数取整

x=int(rand()*5)+5;

谢谢楼上得，我就没有对应过来，class are in, out and inout,但是我在TSL ONline上看到得
extern type function_name ( param1, param2,...);

The type refers to the return value of the function.  Type can be one of the following:

char (signed and unsigned)        float
short (signed and unsigned        double
int (signed and unsigned)        string (equivalent to C char*)
long (signed and unsigned)

Each parameter must include the following information:
[mode] type [name] [< size >]
mode        The mode can be in, out, or inout.  The default is in.  Note that these values must appear in lower case.


这又何解释，当时我就认为 认为Type应该是int。快晕叻。是否在Extern 函数申明中又另一种写法？楼上得有没有相关资料啊。谢谢啦，本人正水深火热中。

I think you are wrong, you need study more

the parameter class are in, out and inout, not int. this is C-like language not standard C language

now if you do not enter the parameter class then the default class is inout

understand ?

hope it help for you

我自己来回答好叻，这个板块的人气很差，就和我那个QQ群一样死气。
