ceventRun编译提示cevent.c(114): error: too many arguments to function call, expected 0, have 1怎么处理呢，只能识别不传参的函数

[WLiangJun]

老师，请教一下，ceventRun编译提示cevent.c(114): error: too many arguments to function call, expected 0, have 1怎么处理呢，只能识别不传参的函数，怎么解决呢。需要根据自己的函数情况做适配吗？能不能帮忙分析解决一下，谢谢

用的是最新的 keil 吧
之前这里传参，使用的函数类型是一个不带参数的函数，原先的 C 对这个类型的函数，可以传递任意的参数数量进去，但是最新的 C 规范已经不允许这种行为了，需要明确定义函数的类型，后面我会更新一版，你可以按照下面的方式自己修改使用

static void ceventRun(CEvent *cevent)
{
    if (cevent->paramNum < 1)
    {
        return;
    }
    switch (cevent->paramNum)
    {
    case 1:
        void (*function)() = (void (*)())(cevent->param[0]);
        function();
        break;
    case 2:
        void (*function)(void *) = (void (*)())(cevent->param[0]);
        function(cevent->param[1]);
        break;
    case 3:
        void (*function)(void *, void *) = (void (*)())(cevent->param[0]);
        function(cevent->param[1], cevent->param[2]);
        break;
    case 4:
        void (*function)(void *, void *, void*) = (void (*)())(cevent->param[0]);
        function(cevent->param[1], cevent->param[2], cevent->param[3]);
        break;
    case 5:
        void (*function)(void *, void *, void*, void*) = (void (*)())(cevent->param[0]);
        function(cevent->param[1], cevent->param[2], cevent->param[3], cevent->param[4]);
        break;
    case 6:
        void (*function)(void *, void *, void*, void*, void*) = (void (*)())(cevent->param[0]);
        function(cevent->param[1], cevent->param[2], cevent->param[3], cevent->param[4],
                 cevent->param[5]);
        break;
    case 7:

        function(cevent->param[1], cevent->param[2], cevent->param[3], cevent->param[4],

        break;
    case 8:

        function(cevent->param[1], cevent->param[2], cevent->param[3], cevent->param[4],
                 cevent->param[5], cevent->param[6], cevent->param[7]);
        break;
    default:
        break;
    }
}

好滴，明白了谢谢大大。还有一个问题，就是使用cevent的时候，对event的请求数量和导出事件数量有限制吗？我看了一下好像没有说性能。有个地方提了一下事件缓存，这个事件缓存指导出的事件函数个数还是ceventpost的请求数呢？谢谢答疑

有个缓存的配置，主要是用来做效率提升的，属于用内存空间换速度，如果开了，就需要注意那个大小配置
大小计算方式注释有写，如果配置小了会发生异常

[WLiangJun]

好的，谢谢大大

[WLiangJun]

大大，我的编译环境要这样才不会报错，贴出来给大家参考：
static void ceventRun(CEvent *cevent)
{
if (cevent->paramNum < 1)
{
return;
}
void (function)() = (void ()())(cevent->param[0]);
switch (cevent->paramNum)
{
case 1:{
function();
break;
}
/后面的需要用再添加/
case 2:{
void (*function2)(void ) = (void ()(void *))(cevent->param[0]);
function2((void *)cevent->param[1]);
break;
}
case 3:{
void (*function3)(void *, void ) = (void ()(void *, void *))(cevent->param[0]);
function3((void *)cevent->param[1], (void *)cevent->param[2]);
break;
}
case 4:{
void (*function4)(void , void , void) = (void ()(void *, void , void))(cevent->param[0]);
function4((void *)cevent->param[1], (void *)cevent->param[2], (void *)cevent->param[3]);
break;
}
case 5:{
void (function5)(void , void , void, void) = (void ()(void , void , void, void))(cevent->param[0]);
function5((void *)cevent->param[1], (void *)cevent->param[2], (void )cevent->param[3], (void )cevent->param[4]);
break;
}
case 6:{
void (function6)(void , void , void, void, void) = (void ()(void , void , void, void, void))(cevent->param[0]);
function6((void *)cevent->param[1], (void )cevent->param[2], (void )cevent->param[3], (void )cevent->param[4],
(void )cevent->param[5]);
break;
}
case 7:{
void (function7)(void , void , void, void, void, void) = (void ()(void , void , void, void, void, void))(cevent->param[0]);
function7((void )cevent->param[1], (void )cevent->param[2], (void )cevent->param[3], (void )cevent->param[4],
(void )cevent->param[5], (void )cevent->param[6]);
break;
}
case 8:{
void (function8)(void , void , void, void, void, void, void) = (void ()(void , void , void, void, void, void, void))(cevent->param[0]);
function8((void *)cevent->param[1], (void *)cevent->param[2], (void *)cevent->param[3], (void *)cevent->param[4],
