C警告 - 内置函数'memcpy'的不兼容隐式声明[默认启用] [英] C Warning - incompatible implicit declaration of built-in function ‘memcpy’ [enabled by default]

问题描述

出于某种原因，我发出警告内置函数'memcpy'的不兼容隐式声明[默认启用]



代码简单如下

 void * p_TelecommandData //这是一个输入变量
 OBCP_PLAN_ID_T t_PlanId; 
 memcpy（（void *）& t_PlanId，p_TelecommandData，sizeof（OBCP_PLAN_ID_T））; 

我包括

 strings.h 

感谢您的帮助

解决方案

假设您正在使用MSVC - 如果您查看文档，您将看到您需要

  #include   <   string.h  >

Hi,

For some reason I am having the warning incompatible implicit declaration of built-in function ‘memcpy’ [enabled by default]

The code is as simple as

void* p_TelecommandData // This is an input variable
OBCP_PLAN_ID_T t_PlanId;
memcpy((void*)&t_PlanId, p_TelecommandData, sizeof(OBCP_PLAN_ID_T));

I am including

strings.h

Thanks for your help

解决方案

Assuming you are using MSVC - If you check the documentation you will see that you need

#include <string.h>
