cpost和cevent移植嵌入式系统

添加源文件头文件至工程

.c及其对应的.h文件

编译环境

keil 5.39   MDK6

编译错误

无法找到size_t

添加#include <stddef.h>  /*size_t*/

ceventRun报错

修改后还是报以下错误怎么解决:

更改如下：需要自己根据具体函数参数个数和函数类型去配置

/**
 * @brief cevent运???
 * 
 * @param cevent cevent
 * 
 */
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:
//        function(cevent->param[1]);
//        break;
//    case 3:
//        function(cevent->param[1], cevent->param[2]);
//        break;
//    case 4:
//        function(cevent->param[1], cevent->param[2], cevent->param[3]);
//        break;
//    case 5:
//        function(cevent->param[1], cevent->param[2], cevent->param[3], cevent->param[4]);
//        break;
//    case 6:
//        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],
//                 cevent->param[5], cevent->param[6]);
//        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;
    }
}

代码终极修复

ok，编译通过

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:{

        function6((void *)cevent->param[1], (void *)cevent->param[2], (void *)cevent->param[3], (void *)cevent->param[4],
                 (void *)cevent->param[5]);
        break;
    }
    case 7:{

        break;
    }
    case 8:{

        function8((void *)cevent->param[1], (void *)cevent->param[2], (void *)cevent->param[3], (void *)cevent->param[4],
                 (void *)cevent->param[5], (void *)cevent->param[6], (void *)cevent->param[7]);
        break;
    }
    default:{
        break;
    }
    }
}

或者替换成下面更统一的方式：

/**

 *

 *

static void ceventRun(CEvent *cevent)
{
    if (cevent->paramNum < 1)

        function();
        break;
    }
    case 2:
    {
        void (*function)(const void *) = (void (*)(const void *))(cevent->param[0]);
        function(cevent->param[1]);
        break;
    }
    case 3:
    {
        void (*function)(const void *, const void *) = (void (*)(const void *, const void *))(cevent->param[0]);
        function(cevent->param[1], cevent->param[2]);
        break;
    }
    case 4:
    {
        void (*function)(const void *, const void *, const void *) = (void (*)(const void *, const void *, const void *))(cevent->param[0]);
        function(cevent->param[1], cevent->param[2], cevent->param[3]);
        break;
    }
    case 5:
    {
        void (*function)(const void *, const void *, const void *, const void *) =
            (void (*)(const void *, const void *, const void *, const void *))(cevent->param[0]);
        function(cevent->param[1], cevent->param[2], cevent->param[3], cevent->param[4]);
        break;
    }
    case 6:
    {
        void (*function)(const void *, const void *, const void *, const void *,
            const void *) = (void (*)(const void *, const void *, const void *, const void *,
            const void *))(cevent->param[0]);
        function(cevent->param[1], cevent->param[2], cevent->param[3], cevent->param[4],
                 cevent->param[5]);
        break;
    }
    case 7:
    {
        void (*function)(const void *, const void *, const void *, const void *,
            const void *, const void *) = (void (*)(const void *, const void *, const void *, const void *,
            const void *, const void *))(cevent->param[0]);
        function(cevent->param[1], cevent->param[2], cevent->param[3], cevent->param[4],
                 cevent->param[5], cevent->param[6]);
        break;
    }
    case 8:
    {
        void (*function)(const void *, const void *, const void *, const void *,
            const void *, const void *, const void *) = (void (*)(const void *, const void *, const void *, const void *,
